2010-06-24HID: magicmouse: add param for scroll speedChase Douglas
The new scroll_speed param takes an integer value from 0 to 63, where 0 is slowest and 63 is fastest. The default of 32 remains the same. This parameter also affects scroll acceleration linearly. A second part of this change is a tightly coupled modification to the scroll acceleration. Previously, scroll acceleration could be reset without lifting the scroll finger. This is rather unintuitive and hard to control in the case where a user wants faster scrolling, but wants to hold the scroll touch for longer than a moment. Note that scroll acceleration levels are now 1-7, where 7 is slowest. In the previous implementation, there were 8 levels defined, but it was impossible to start at the slowest level. In order to keep the default scroll speed unchanged, only 7 levels are used now.

2010-06-04HID: magicmouse: scroll on entire surface, not just middle of mouseChase Douglas
Previously, scroll events only occurred when the user moved a touch along the middle of the touch surface. This is unintuitive for a normal user who is not aware of this. The device has a uniform surface, so the distinction is artificial. This change removes the touch area check for a scroll event, which replicates the OS X behavior.

2010-06-04HID: check for HID_QUIRK_IGNORE during probingJindrich Makovicka
While the hardcoded ignore list is checked in hid_add_device(), the user supplied ignore flags are not. Thus, the IGNORE quirk (0x0004) cannot be used to stop usbhid from binding devices like iBuddy, which has been recently removed from the ignore list due to product ID conflict. This patch adds the user quirk check to hid_add_device(), and makes hid_add_device() return -ENODEV when HID_QUIRK_IGNORE bit is set. HID_QUIRK_NO_IGNORE still takes precedence over HID_QUIRK_IGNORE. With the patch, iBuddy works properly using libusb when the following option is added to modprobe.d: options usbhid quirks=0x1130:0x0002:0x0004 Signed-off-by: Jindrich Makovicka <makovick@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2010-05-25HID: roccat: propagate special events of roccat hardware to userspaceStefan Achatz
Module roccat is a char device used to report special events of roccat hardware to userland. These events include requests for on-screen-display of profile or dpi settings or requests for execution of macro sequences that are not stored in device. The information in these events depends on hid device implementation and contains data that is not available in a single hid event or else hidraw could have been used. It is inspired by hidraw, but uses only one circular buffer for all readers. The device is as generic as possible so that the functionality is usable by all (kone and upcomming) roccat device drivers.

2010-05-21HID: fix up 'EMBEDDED' mess in KconfigJiri Kosina
The whole point of making some of the drivers automatically selected unless 'EMBEDDED' was to handle quirks transparently after their separation from the generic core. Over time, some of the later-added quirks grew into more standalone drivers, implementing non-trivial features a being larger than a few bytes of code. In addition to that, some of the standalone drivers don't make sense for 99.9% of the users, as they are very specific to rare devices. Therefore build by default in only those drivers which - we historically used to support even before quirk separation from the core code - are isolated enough and likely to hit quite large portion of the users anyway (Microsoft, Logitech) Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2010-05-20USB: remove uses of URB_NO_SETUP_DMA_MAPAlan Stern
This patch (as1350) removes all usages of coherent buffers for USB control-request setup-packet buffers. There's no good reason to reserve coherent memory for these things; control requests are hardly ever used in large quantity (the major exception is firmware transfers, and they aren't time-critical). Furthermore, only seven drivers used it. We might as well always use streaming DMA mappings for setup-packet buffers, and remove some extra complexity from usbcore. The DMA-mapping portion of hcd.c is currently in flux. A separate patch will be submitted to remove support for URB_NO_SETUP_DMA_MAP after everything else settles down. The removal should go smoothly, as by then nobody will be using it. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-05-18HID: hidraw: Use Interrupt Endpoint for OUT Transfers if AvailableAlan Ott
This patch makes the hidraw driver use the first Interrupt OUT endpoint for HID transfers to the device if such an endpoint exists. This is consistent with the behavior of the hiddev driver, and the logic is similar. From the USB HID specification: The Interrupt Out pipe is optional. If a device declares an Interrupt Out endpoint then Output reports are transmitted by the host to the device through the Interrupt Out endpoint. If no Interrupt Out endpoint is declared then Output reports are transmitted to a device through the Control endpoint, using Set_Report(Output) requests.

2010-05-12HID: magicmouse: fix input registrationJiri Kosina
When HIDRAW is not set, hid_hw_start() returns ENODEV as no subsystem has claimed the magicmouse device, and probe routine bails out. Which is not what we want. This happens because magicmouse driver is instantiating the connection to Input subsystem itself, and since commit 28918c211d86b ("HID: magicmouse: fix oops after device removal") the HID core is not registering input device itself. Fix this by letting HID core register the input device (so that hid_hw_start() succeeds, as the device is claimed by at least one subsystem) and de-register it again later before proceeding with proper input setup.
