+ * "Wake-On-LAN" Ethernet links, GPIO lines, and more. Some events
+ * will wake the entire system from a suspend state; others may just
+ * wake up the device (if the system as a whole is already active).
+ * Some wakeup events use normal IRQ lines; other use special out
+ * of band signaling.
+ *
+ * It is the responsibility of device drivers to enable (or disable)
+ * wakeup signaling as part of changing device power states, respecting
+ * the policy choices provided through the driver model.

+ * Devices may not be able to generate wakeup events from all power

+ * for example, they might need help from other devices that aren't
+ * active, or which may have wakeup disabled. Some drivers rely on

- *
- * USB Bluetooth TTY driver, based on the Bluetooth Spec version 1.0B
- *
- * (2001/11/30) Version 0.13 gkh
- * - added locking patch from Masoodur Rahman <rmasoodu@in.ibm.com>
- * - removed active variable, as open_count will do.
- *
- * (2001/07/09) Version 0.12 gkh
- * - removed in_interrupt() call, as it doesn't make sense to do
- * that anymore.
- *
- * (2001/06/05) Version 0.11 gkh
- * - Fixed problem with read urb status saying that we have shutdown,
- * and that we shouldn't resubmit the urb. Patch from unknown.
- *
- * (2001/05/28) Version 0.10 gkh
- * - Fixed problem with using data from userspace in the bluetooth_write
- * function as found by the CHECKER project.
- * - Added a buffer to the write_urb_pool which reduces the number of
- * buffers being created and destroyed for ever write. Also cleans
- * up the logic a bit.
- * - Added a buffer to the control_urb_pool which fixes a memory leak
- * when the device is removed from the system.
- *
- * (2001/05/28) Version 0.9 gkh
- * Fixed problem with bluetooth==NULL for bluetooth_read_bulk_callback
- * which was found by both the CHECKER project and Mikko Rahkonen.
- *
- * (08/04/2001) gb
- * Identify version on module load.
- *
- * (2001/03/10) Version 0.8 gkh
- * Fixed problem with not unlinking interrupt urb on device close
- * and resubmitting the read urb on error with bluetooth struct.
- * Thanks to Narayan Mohanram <narayan@RovingNetworks.com> for the
- * fixes.
- *
- * (11/29/2000) Version 0.7 gkh
- * Fixed problem with overrunning the tty flip buffer.
- * Removed unneeded NULL pointer initialization.
- *
- * (10/05/2000) Version 0.6 gkh
- * Fixed bug with urb->dev not being set properly, now that the usb
- * core needs it.
- * Got a real major id number and name.
- *
- * (08/06/2000) Version 0.5 gkh
- * Fixed problem of not resubmitting the bulk read urb if there is
- * an error in the callback. Ericsson devices seem to need this.
- *
- * (07/11/2000) Version 0.4 gkh
- * Fixed bug in disconnect for when we call tty_hangup
- * Fixed bug in bluetooth_ctrl_msg where the bluetooth struct was not
- * getting attached to the control urb properly.
- * Fixed bug in bluetooth_write where we pay attention to the result
- * of bluetooth_ctrl_msg.
- *
- * (08/03/2000) Version 0.3 gkh mdc
- * Merged in Mark's changes to make the driver play nice with the Axis
- * stack.
- * Made the write bulk use an urb pool to enable larger transfers with
- * fewer calls to the driver.
- * Fixed off by one bug in acl pkt receive
- * Made packet counters specific to each bluetooth device
- * Added checks for zero length callbacks
- * Added buffers for int and bulk packets. Had to do this otherwise
- * packet types could intermingle.
- * Made a control urb pool for the control messages.
- *
- * (07/11/2000) Version 0.2 gkh
- * Fixed a small bug found by Nils Faerber in the usb_bluetooth_probe
- * function.
- *
- * (07/09/2000) Version 0.1 gkh
- * Initial release. Has support for sending ACL data (which is really just
- * a HCI frame.) Raw HCI commands and HCI events are not supported.
- * A ioctl will probably be needed for the HCI commands and events in the
- * future. All isoch endpoints are ignored at this time also.
- * This driver should work for all currently shipping USB Bluetooth
- * devices at this time :)

+-----------------------------------------------------------------------
+usb-serial.c Change Log comments:
+
+ (12/10/2002) gkh
+ Split the ports off into their own struct device, and added a
+ usb-serial bus driver.
+
+ (11/19/2002) gkh
+ removed a few #ifdefs for the generic code and cleaned up the failure
+ logic in initialization.
+
+ (10/02/2002) gkh
+ moved the console code to console.c and out of this file.
+
+ (06/05/2002) gkh
+ moved location of startup() call in serial_probe() until after all
+ of the port information and endpoints are initialized. This makes
+ things easier for some drivers.
+
+ (04/10/2002) gkh
+ added serial_read_proc function which creates a
+ /proc/tty/driver/usb-serial file.
+
+ (03/27/2002) gkh
+ Got USB serial console code working properly and merged into the main
+ version of the tree. Thanks to Randy Dunlap for the initial version
+ of this code, and for pushing me to finish it up.
+ The USB serial console works with any usb serial driver device.
+
+ (03/21/2002) gkh
+ Moved all manipulation of port->open_count into the core. Now the
+ individual driver's open and close functions are called only when the
+ first open() and last close() is called. Making the drivers a bit
+ smaller and simpler.
+ Fixed a bug if a driver didn't have the owner field set.
+
+ (02/26/2002) gkh
+ Moved all locking into the main serial_* functions, instead of having
+ the individual drivers have to grab the port semaphore. This should
+ reduce races.
+ Reworked the MOD_INC logic a bit to always increment and decrement, even
+ if the generic driver is being used.
+
+ (10/10/2001) gkh
+ usb_serial_disconnect() now sets the serial->dev pointer is to NULL to
+ help prevent child drivers from accessing the device since it is now
+ gone.
+
+ (09/13/2001) gkh
+ Moved generic driver initialize after we have registered with the USB
+ core. Thanks to Randy Dunlap for pointing this problem out.
+
+ (07/03/2001) gkh
+ Fixed module paramater size. Thanks to John Brockmeyer for the pointer.
+ Fixed vendor and product getting defined through the MODULE_PARM macro
+ if the Generic driver wasn't compiled in.
+ Fixed problem with generic_shutdown() not being called for drivers that
+ don't have a shutdown() function.
+
+ (06/06/2001) gkh
+ added evil hack that is needed for the prolific pl2303 device due to the
+ crazy way its endpoints are set up.
+
+ (05/30/2001) gkh
+ switched from using spinlock to a semaphore, which fixes lots of problems.
+
+ (04/08/2001) gb
+ Identify version on module load.
+
+ 2001_02_05 gkh
+ Fixed buffer overflows bug with the generic serial driver. Thanks to
+ Todd Squires <squirest@ct0.com> for fixing this.
+
+ (01/10/2001) gkh
+ Fixed bug where the generic serial adaptor grabbed _any_ device that was
+ offered to it.
+
+ (12/12/2000) gkh
+ Removed MOD_INC and MOD_DEC from poll and disconnect functions, and
+ moved them to the serial_open and serial_close functions.
+ Also fixed bug with there not being a MOD_DEC for the generic driver
+ (thanks to Gary Brubaker for finding this.)
+
+ (11/29/2000) gkh
+ Small NULL pointer initialization cleanup which saves a bit of disk image
+
+ (11/01/2000) Adam J. Richter
+ instead of using idVendor/idProduct pairs, usb serial drivers
+ now identify their hardware interest with usb_device_id tables,
+ which they usually have anyhow for use with MODULE_DEVICE_TABLE.
+
+ (10/05/2000) gkh
+ Fixed bug with urb->dev not being set properly, now that the usb
+ core needs it.
+
+ (09/11/2000) gkh
+ Removed DEBUG #ifdefs with call to usb_serial_debug_data
+
+ (08/28/2000) gkh
+ Added port_lock to port structure.
+ Added locks for SMP safeness to generic driver
+ Fixed the ability to open a generic device's port more than once.
+
+ (07/23/2000) gkh
+ Added bulk_out_endpointAddress to port structure.
+
+ (07/19/2000) gkh, pberger, and borchers
+ Modifications to allow usb-serial drivers to be modules.
+
+ (07/03/2000) gkh
+ Added more debugging to serial_ioctl call
+
+ (06/25/2000) gkh
+ Changed generic_write_bulk_callback to not call wake_up_interruptible
+ directly, but to have port_softint do it at a safer time.
+
+ (06/23/2000) gkh
+ Cleaned up debugging statements in a quest to find UHCI timeout bug.
+
+ (05/22/2000) gkh
+ Changed the makefile, enabling the big CONFIG_USB_SERIAL_SOMTHING to be
+ removed from the individual device source files.
+
+ (05/03/2000) gkh
+ Added the Digi Acceleport driver from Al Borchers and Peter Berger.
+
+ (05/02/2000) gkh
+ Changed devfs and tty register code to work properly now. This was based on
+ the ACM driver changes by Vojtech Pavlik.
+
+ (04/27/2000) Ryan VanderBijl
+ Put calls to *_paranoia_checks into one function.
+
+ (04/23/2000) gkh
+ Fixed bug that Randy Dunlap found for Generic devices with no bulk out ports.
+ Moved when the startup code printed out the devices that are supported.
+
+ (04/19/2000) gkh
+ Added driver for ZyXEL omni.net lcd plus ISDN TA
+ Made startup info message specify which drivers were compiled in.
+
+ (04/03/2000) gkh
+ Changed the probe process to remove the module unload races.
+ Changed where the tty layer gets initialized to have devfs work nicer.
+ Added initial devfs support.
+
+ (03/26/2000) gkh
+ Split driver up into device specific pieces.
+
+ (03/19/2000) gkh
+ Fixed oops that could happen when device was removed while a program
+ was talking to the device.
+ Removed the static urbs and now all urbs are created and destroyed
+ dynamically.
+ Reworked the internal interface. Now everything is based on the
+ usb_serial_port structure instead of the larger usb_serial structure.
+ This fixes the bug that a multiport device could not have more than
+ one port open at one time.
+
+ (03/17/2000) gkh
+ Added config option for debugging messages.
+ Added patch for keyspan pda from Brian Warner.
+
+ (03/06/2000) gkh
+ Added the keyspan pda code from Brian Warner <warner@lothar.com>
+ Moved a bunch of the port specific stuff into its own structure. This
+ is in anticipation of the true multiport devices (there's a bug if you
+ try to access more than one port of any multiport device right now)
+
+ (02/21/2000) gkh
+ Made it so that any serial devices only have to specify which functions
+ they want to overload from the generic function calls (great,
+ inheritance in C, in a driver, just what I wanted...)
+ Added support for set_termios and ioctl function calls. No drivers take
+ advantage of this yet.
+ Removed the #ifdef MODULE, now there is no module specific code.
+ Cleaned up a few comments in usb-serial.h that were wrong (thanks again
+ to Miles Lott).
+ Small fix to get_free_serial.
+
+ (02/14/2000) gkh
+ Removed the Belkin and Peracom functionality from the driver due to
+ the lack of support from the vendor, and me not wanting people to
+ accidenatly buy the device, expecting it to work with Linux.
+ Added read_bulk_callback and write_bulk_callback to the type structure
+ for the needs of the FTDI and WhiteHEAT driver.
+ Changed all reverences to FTDI to FTDI_SIO at the request of Bill
+ Ryder.
+ Changed the output urb size back to the max endpoint size to make
+ the ftdi_sio driver have it easier, and due to the fact that it didn't
+ really increase the speed any.
+
+ (02/11/2000) gkh
+ Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a
+ patch from Miles Lott (milos@insync.net).
+ Fixed bug with not restoring the minor range that a device grabs, if
+ the startup function fails (thanks Miles for finding this).
+
+ (02/05/2000) gkh
+ Added initial framework for the Keyspan PDA serial converter so that
+ Brian Warner has a place to put his code.
+ Made the ezusb specific functions generic enough that different
+ devices can use them (whiteheat and keyspan_pda both need them).
+ Split out a whole bunch of structure and other stuff to a separate
+ usb-serial.h file.
+ Made the Visor connection messages a little more understandable, now
+ that Miles Lott (milos@insync.net) has gotten the Generic channel to
+ work. Also made them always show up in the log file.
+
+ (01/25/2000) gkh
+ Added initial framework for FTDI serial converter so that Bill Ryder
+ has a place to put his code.
+ Added the vendor specific info from Handspring. Now we can print out
+ informational debug messages as well as understand what is happening.
+
+ (01/23/2000) gkh
+ Fixed problem of crash when trying to open a port that didn't have a
+ device assigned to it. Made the minor node finding a little smarter,
+ now it looks to find a continuous space for the new device.
+
+ (01/21/2000) gkh
+ Fixed bug in visor_startup with patch from Miles Lott (milos@insync.net)
+ Fixed get_serial_by_minor which was all messed up for multi port
+ devices. Fixed multi port problem for generic devices. Now the number
+ of ports is determined by the number of bulk out endpoints for the
+ generic device.
+
+ (01/19/2000) gkh
+ Removed lots of cruft that was around from the old (pre urb) driver
+ interface.
+ Made the serial_table dynamic. This should save lots of memory when
+ the number of minor nodes goes up to 256.
+ Added initial support for devices that have more than one port.
+ Added more debugging comments for the Visor, and added a needed
+ set_configuration call.
+
+ (01/17/2000) gkh
+ Fixed the WhiteHEAT firmware (my processing tool had a bug)
+ and added new debug loader firmware for it.
+ Removed the put_char function as it isn't really needed.
+ Added visor startup commands as found by the Win98 dump.
+
+ (01/13/2000) gkh
+ Fixed the vendor id for the generic driver to the one I meant it to be.
+
+ (01/12/2000) gkh
+ Forget the version numbering...that's pretty useless...
+ Made the driver able to be compiled so that the user can select which
+ converter they want to use. This allows people who only want the Visor
+ support to not pay the memory size price of the WhiteHEAT.
+ Fixed bug where the generic driver (idVendor=0000 and idProduct=0000)
+ grabbed the root hub. Not good.
+
+ version 0.4.0 (01/10/2000) gkh
+ Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT
+ device. Added startup function to allow firmware to be downloaded to
+ a device if it needs to be.
+ Added firmware download logic to the WhiteHEAT device.
+ Started to add #defines to split up the different drivers for potential
+ configuration option.
+
+ version 0.3.1 (12/30/99) gkh
+ Fixed problems with urb for bulk out.
+ Added initial support for multiple sets of endpoints. This enables
+ the Handspring Visor to be attached successfully. Only the first
+ bulk in / bulk out endpoint pair is being used right now.
+
+ version 0.3.0 (12/27/99) gkh
+ Added initial support for the Handspring Visor based on a patch from
+ Miles Lott (milos@sneety.insync.net)
+ Cleaned up the code a bunch and converted over to using urbs only.
+
+ version 0.2.3 (12/21/99) gkh
+ Added initial support for the Connect Tech WhiteHEAT converter.
+ Incremented the number of ports in expectation of getting the
+ WhiteHEAT to work properly (4 ports per connection).
+ Added notification on insertion and removal of what port the
+ device is/was connected to (and what kind of device it was).
+
+ version 0.2.2 (12/16/99) gkh
+ Changed major number to the new allocated number. We're legal now!
+
+ version 0.2.1 (12/14/99) gkh
+ Fixed bug that happens when device node is opened when there isn't a
+ device attached to it. Thanks to marek@webdesign.no for noticing this.
+
+ version 0.2.0 (11/10/99) gkh
+ Split up internals to make it easier to add different types of serial
+ converters to the code.
+ Added a "generic" driver that gets it's vendor and product id
+ from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net)
+ for the idea and sample code (from the usb scanner driver.)
+ Cleared up any licensing questions by releasing it under the GNU GPL.
+
+ version 0.1.2 (10/25/99) gkh
+ Fixed bug in detecting device.
+
+ version 0.1.1 (10/05/99) gkh
+ Changed the major number to not conflict with anything else.
+
+ version 0.1 (09/28/99) gkh
+ Can recognize the two different devices and start up a read from
+ device when asked to. Writes also work. No control signals yet, this
+ all is vendor specific data (i.e. no spec), also no control for
+ different baud rates or other bit settings.
+ Currently we are using the same devid as the acm driver. This needs
+ to change.
+

+ Added support for the Palm i705 device, thanks to Thomas Riemer
+ <tom@netmech.com> for the information.

+ <udo.eisenbarth@web.de> for the information.
+
+ (02/27/2002) gkh
+ Reworked the urb handling logic. We have no more pool, but dynamically
+ allocate the urb and the transfer buffer on the fly. In testing this
+ does not incure any measurable overhead. This also relies on the fact
+ that we have proper reference counting logic for urbs.
+
+ (02/21/2002) SilaS
+ Added initial support for the Palm m515 devices.
+
+ (02/14/2002) gkh

+ (08/30/2001) gkh
+ Added support for the Clie devices, both the 3.5 and 4.0 os versions.
+ Many thanks to Daniel Burke, and Bryan Payne for helping with this.
+
+ (08/23/2001) gkh
+ fixed a few potential bugs pointed out by Oliver Neukum.
+
+ (05/30/2001) gkh

+
+ (05/28/2000) gkh
+ Added initial support for the Palm m500 and Palm m505 devices.
+
+ (04/08/2001) gb
+ Identify version on module load.
+
+ (01/21/2000) gkh
+ Added write_room and chars_in_buffer, as they were previously using the
+ generic driver versions which is all wrong now that we are using an urb
+ pool. Thanks to Wolfgang Grandegger for pointing this out to me.
+ Removed count assignment in the write function, which was not needed anymore
+ either. Thanks to Al Borchers for pointing this out.
+
+ (12/12/2000) gkh
+ Moved MOD_DEC to end of visor_close to be nicer, as the final write
+ message can sleep.
+
+ (11/12/2000) gkh
+ Fixed bug with data being dropped on the floor by forcing tty->low_latency
+ to be on. Hopefully this fixes the OHCI issue!
+
+ (11/01/2000) Adam J. Richter
+ usb_device_id table support
+
+ (10/05/2000) gkh
+ Fixed bug with urb->dev not being set properly, now that the usb
+ core needs it.
+
+ (09/11/2000) gkh
+ Got rid of always calling kmalloc for every urb we wrote out to the
+ device.
+ Added visor_read_callback so we can keep track of bytes in and out for
+ those people who like to know the speed of their device.
+ Removed DEBUG #ifdefs with call to usb_serial_debug_data
+
+ (09/06/2000) gkh
+ Fixed oops in visor_exit. Need to uncomment usb_unlink_urb call _after_
+ the host controller drivers set urb->dev = NULL when the urb is finished.
+
+ (08/28/2000) gkh
+ Added locks for SMP safeness.
+
+ (08/08/2000) gkh
+ Fixed endian problem in visor_startup.
+ Fixed MOD_INC and MOD_DEC logic and the ability to open a port more
+ than once.
+
+ (07/23/2000) gkh
+ Added pool of write urbs to speed up transfers to the visor.
+
+ (07/19/2000) gkh
+ Added module_init and module_exit functions to handle the fact that this
+ driver is a loadable module now.
+
+ (07/03/2000) gkh
+ Added visor_set_ioctl and visor_set_termios functions (they don't do much
+ of anything, but are good for debugging.)
+
+ (06/25/2000) gkh
+ Fixed bug in visor_unthrottle that should help with the disconnect in PPP
+ bug that people have been reporting.
+
+ (06/23/2000) gkh
+ Cleaned up debugging statements in a quest to find UHCI timeout bug.
+
+ (04/27/2000) Ryan VanderBijl

+
+-----------------------------------------------------------------------
+pl2303.c Change Log comments:
+
+ 2002_Mar_26 gkh
+ allowed driver to work properly if there is no tty assigned to a port

+ 2001_Oct_06 gkh
+ Added RTS and DTR line control. Thanks to joe@bndlg.de for parts of it.
+
+ 2001_Sep_19 gkh

+
+ 2001_Aug_30 gkh

+ Milestone 1 release.
+ Device is found by USB subsystem, enumerated, fimware is downloaded
+ and the descriptors are printed to the debug log, config is set, and
+ green light starts to blink. Open port works, and data can be sent
+ and received at the default settings of the UART. Loopback connector
+ and debug log confirms this.
+
+ 0.1 (01/23/2000) greg kroah-hartman
+ Initial release to help IO Networks try to set up their test system.
+ Edgeport4 is recognized, firmware is downloaded, config is set so
+ device blinks green light every 3 sec. Port is bound, but opening,
+ closing, and sending data do not work properly.

- * (06/05/2002) gkh
- * moved location of startup() call in serial_probe() until after all
- * of the port information and endpoints are initialized. This makes
- * things easier for some drivers.
- *
- * (04/10/2002) gkh
- * added serial_read_proc function which creates a

- *
- * (03/27/2002) gkh
- * Got USB serial console code working properly and merged into the main
- * version of the tree. Thanks to Randy Dunlap for the initial version
- * of this code, and for pushing me to finish it up.
- * The USB serial console works with any usb serial driver device.
- *
- * (03/21/2002) gkh
- * Moved all manipulation of port->open_count into the core. Now the
- * individual driver's open and close functions are called only when the
- * first open() and last close() is called. Making the drivers a bit
- * smaller and simpler.
- * Fixed a bug if a driver didn't have the owner field set.
- *
- * (02/26/2002) gkh
- * Moved all locking into the main serial_* functions, instead of having
- * the individual drivers have to grab the port semaphore. This should
- * reduce races.
- * Reworked the MOD_INC logic a bit to always increment and decrement, even
- * if the generic driver is being used.
- *
- * (10/10/2001) gkh
- * usb_serial_disconnect() now sets the serial->dev pointer is to NULL to
- * help prevent child drivers from accessing the device since it is now
- * gone.
- *
- * (09/13/2001) gkh
- * Moved generic driver initialize after we have registered with the USB
- * core. Thanks to Randy Dunlap for pointing this problem out.
- *
- * (07/03/2001) gkh
- * Fixed module paramater size. Thanks to John Brockmeyer for the pointer.
- * Fixed vendor and product getting defined through the MODULE_PARM macro
- * if the Generic driver wasn't compiled in.
- * Fixed problem with generic_shutdown() not being called for drivers that
- * don't have a shutdown() function.
- *
- * (06/06/2001) gkh
- * added evil hack that is needed for the prolific pl2303 device due to the
- * crazy way its endpoints are set up.
- *
- * (05/30/2001) gkh
- * switched from using spinlock to a semaphore, which fixes lots of problems.

- * 2001_02_05 gkh
- * Fixed buffer overflows bug with the generic serial driver. Thanks to

- *
- * (01/10/2001) gkh
- * Fixed bug where the generic serial adaptor grabbed _any_ device that was
- * offered to it.
- *
- * (12/12/2000) gkh
- * Removed MOD_INC and MOD_DEC from poll and disconnect functions, and
- * moved them to the serial_open and serial_close functions.
- * Also fixed bug with there not being a MOD_DEC for the generic driver
- * (thanks to Gary Brubaker for finding this.)

- * (11/29/2000) gkh
- * Small NULL pointer initialization cleanup which saves a bit of disk image
- *
- * (11/01/2000) Adam J. Richter
- * instead of using idVendor/idProduct pairs, usb serial drivers
- * now identify their hardware interest with usb_device_id tables,
- * which they usually have anyhow for use with MODULE_DEVICE_TABLE.

- * (10/05/2000) gkh
- * Fixed bug with urb->dev not being set properly, now that the usb
- * core needs it.

- * (09/11/2000) gkh
- * Removed DEBUG #ifdefs with call to usb_serial_debug_data
- *
- * (08/28/2000) gkh
- * Added port_lock to port structure.
- * Added locks for SMP safeness to generic driver
- * Fixed the ability to open a generic device's port more than once.
- *
- * (07/23/2000) gkh
- * Added bulk_out_endpointAddress to port structure.
- *
- * (07/19/2000) gkh, pberger, and borchers
- * Modifications to allow usb-serial drivers to be modules.
- *
- * (07/03/2000) gkh
- * Added more debugging to serial_ioctl call
- *
- * (06/25/2000) gkh
- * Changed generic_write_bulk_callback to not call wake_up_interruptible
- * directly, but to have port_softint do it at a safer time.
- *
- * (06/23/2000) gkh
- * Cleaned up debugging statements in a quest to find UHCI timeout bug.
- *
- * (05/22/2000) gkh
- * Changed the makefile, enabling the big CONFIG_USB_SERIAL_SOMTHING to be
- * removed from the individual device source files.
- *
- * (05/03/2000) gkh
- * Added the Digi Acceleport driver from Al Borchers and Peter Berger.
- *
- * (05/02/2000) gkh
- * Changed devfs and tty register code to work properly now. This was based on
- * the ACM driver changes by Vojtech Pavlik.
- *
- * (04/27/2000) Ryan VanderBijl
- * Put calls to *_paranoia_checks into one function.
- *
- * (04/23/2000) gkh
- * Fixed bug that Randy Dunlap found for Generic devices with no bulk out ports.
- * Moved when the startup code printed out the devices that are supported.
- *
- * (04/19/2000) gkh
- * Added driver for ZyXEL omni.net lcd plus ISDN TA
- * Made startup info message specify which drivers were compiled in.
- *
- * (04/03/2000) gkh
- * Changed the probe process to remove the module unload races.
- * Changed where the tty layer gets initialized to have devfs work nicer.
- * Added initial devfs support.
- *
- * (03/26/2000) gkh
- * Split driver up into device specific pieces.
- *
- * (03/19/2000) gkh
- * Fixed oops that could happen when device was removed while a program
- * was talking to the device.
- * Removed the static urbs and now all urbs are created and destroyed
- * dynamically.
- * Reworked the internal interface. Now everything is based on the
- * usb_serial_port structure instead of the larger usb_serial structure.
- * This fixes the bug that a multiport device could not have more than
- * one port open at one time.
- *
- * (03/17/2000) gkh
- * Added config option for debugging messages.
- * Added patch for keyspan pda from Brian Warner.
- *
- * (03/06/2000) gkh
- * Added the keyspan pda code from Brian Warner <warner@lothar.com>
- * Moved a bunch of the port specific stuff into its own structure. This
- * is in anticipation of the true multiport devices (there's a bug if you
- * try to access more than one port of any multiport device right now)
- *
- * (02/21/2000) gkh
- * Made it so that any serial devices only have to specify which functions
- * they want to overload from the generic function calls (great,
- * inheritance in C, in a driver, just what I wanted...)
- * Added support for set_termios and ioctl function calls. No drivers take
- * advantage of this yet.
- * Removed the #ifdef MODULE, now there is no module specific code.
- * Cleaned up a few comments in usb-serial.h that were wrong (thanks again
- * to Miles Lott).
- * Small fix to get_free_serial.
- *
- * (02/14/2000) gkh
- * Removed the Belkin and Peracom functionality from the driver due to
- * the lack of support from the vendor, and me not wanting people to
- * accidenatly buy the device, expecting it to work with Linux.
- * Added read_bulk_callback and write_bulk_callback to the type structure
- * for the needs of the FTDI and WhiteHEAT driver.
- * Changed all reverences to FTDI to FTDI_SIO at the request of Bill
- * Ryder.
- * Changed the output urb size back to the max endpoint size to make
- * the ftdi_sio driver have it easier, and due to the fact that it didn't
- * really increase the speed any.
- *
- * (02/11/2000) gkh
- * Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a
- * patch from Miles Lott (milos@insync.net).
- * Fixed bug with not restoring the minor range that a device grabs, if
- * the startup function fails (thanks Miles for finding this).
- *
- * (02/05/2000) gkh
- * Added initial framework for the Keyspan PDA serial converter so that
- * Brian Warner has a place to put his code.
- * Made the ezusb specific functions generic enough that different
- * devices can use them (whiteheat and keyspan_pda both need them).
- * Split out a whole bunch of structure and other stuff to a separate
- * usb-serial.h file.
- * Made the Visor connection messages a little more understandable, now
- * that Miles Lott (milos@insync.net) has gotten the Generic channel to
- * work. Also made them always show up in the log file.
- *
- * (01/25/2000) gkh
- * Added initial framework for FTDI serial converter so that Bill Ryder
- * has a place to put his code.
- * Added the vendor specific info from Handspring. Now we can print out
- * informational debug messages as well as understand what is happening.
- *
- * (01/23/2000) gkh
- * Fixed problem of crash when trying to open a port that didn't have a
- * device assigned to it. Made the minor node finding a little smarter,
- * now it looks to find a continuous space for the new device.
- *
- * (01/21/2000) gkh
- * Fixed bug in visor_startup with patch from Miles Lott (milos@insync.net)
- * Fixed get_serial_by_minor which was all messed up for multi port
- * devices. Fixed multi port problem for generic devices. Now the number
- * of ports is determined by the number of bulk out endpoints for the
- * generic device.
- *
- * (01/19/2000) gkh
- * Removed lots of cruft that was around from the old (pre urb) driver
- * interface.
- * Made the serial_table dynamic. This should save lots of memory when
- * the number of minor nodes goes up to 256.
- * Added initial support for devices that have more than one port.
- * Added more debugging comments for the Visor, and added a needed
- * set_configuration call.
- *
- * (01/17/2000) gkh
- * Fixed the WhiteHEAT firmware (my processing tool had a bug)
- * and added new debug loader firmware for it.
- * Removed the put_char function as it isn't really needed.
- * Added visor startup commands as found by the Win98 dump.
- *
- * (01/13/2000) gkh
- * Fixed the vendor id for the generic driver to the one I meant it to be.
- *
- * (01/12/2000) gkh
- * Forget the version numbering...that's pretty useless...
- * Made the driver able to be compiled so that the user can select which
- * converter they want to use. This allows people who only want the Visor
- * support to not pay the memory size price of the WhiteHEAT.
- * Fixed bug where the generic driver (idVendor=0000 and idProduct=0000)
- * grabbed the root hub. Not good.
- *
- * version 0.4.0 (01/10/2000) gkh
- * Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT
- * device. Added startup function to allow firmware to be downloaded to
- * a device if it needs to be.
- * Added firmware download logic to the WhiteHEAT device.
- * Started to add #defines to split up the different drivers for potential
- * configuration option.
- *
- * version 0.3.1 (12/30/99) gkh
- * Fixed problems with urb for bulk out.
- * Added initial support for multiple sets of endpoints. This enables
- * the Handspring Visor to be attached successfully. Only the first
- * bulk in / bulk out endpoint pair is being used right now.
- *
- * version 0.3.0 (12/27/99) gkh
- * Added initial support for the Handspring Visor based on a patch from
- * Miles Lott (milos@sneety.insync.net)
- * Cleaned up the code a bunch and converted over to using urbs only.
- *
- * version 0.2.3 (12/21/99) gkh
- * Added initial support for the Connect Tech WhiteHEAT converter.
- * Incremented the number of ports in expectation of getting the
- * WhiteHEAT to work properly (4 ports per connection).
- * Added notification on insertion and removal of what port the
- * device is/was connected to (and what kind of device it was).
- *
- * version 0.2.2 (12/16/99) gkh
- * Changed major number to the new allocated number. We're legal now!
- *
- * version 0.2.1 (12/14/99) gkh
- * Fixed bug that happens when device node is opened when there isn't a
- * device attached to it. Thanks to marek@webdesign.no for noticing this.
- *
- * version 0.2.0 (11/10/99) gkh
- * Split up internals to make it easier to add different types of serial
- * converters to the code.
- * Added a "generic" driver that gets it's vendor and product id
- * from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net)
- * for the idea and sample code (from the usb scanner driver.)
- * Cleared up any licensing questions by releasing it under the GNU GPL.
- *
- * version 0.1.2 (10/25/99) gkh
- * Fixed bug in detecting device.
- *
- * version 0.1.1 (10/05/99) gkh
- * Changed the major number to not conflict with anything else.
- *
- * version 0.1 (09/28/99) gkh
- * Can recognize the two different devices and start up a read from
- * device when asked to. Writes also work. No control signals yet, this
- * all is vendor specific data (i.e. no spec), also no control for
- * different baud rates or other bit settings.
- * Currently we are using the same devid as the acm driver. This needs
- * to change.

- *
- * (06/25/2000) gkh
- * Fixed bug in visor_unthrottle that should help with the disconnect in PPP
- * bug that people have been reporting.
- *
- * (06/23/2000) gkh
- * Cleaned up debugging statements in a quest to find UHCI timeout bug.
- *
- * (04/27/2000) Ryan VanderBijl
- * Fixed memory leak in visor_close
- *
- * (03/26/2000) gkh
- * Split driver up into device specific pieces.
