+/* This file provides translation primitives and tables for the conversion
+ * of (ASCII) characters to a 7-segments notation.
+ *
+ * The 7 segment's wikipedia notation below is used as standard.
+ * See: http://en.wikipedia.org/wiki/Seven_segment_display
+ *
+ * Notation: +-a-+
+ * f b
+ * +-g-+
+ * e c
+ * +-d-+
+ *
+ * Usage:
+ *
+ * Register a map variable, and fill it with a character set:
+ * static SEG7_DEFAULT_MAP(map_seg7);
+ *
+ *
+ * Then use for conversion:
+ * seg7 = map_to_seg7(&map_seg7, some_char);
+ * ...
+ *
+ * In device drivers it is recommended, if required, to make the char map
+ * accessible via the sysfs interface using the following scheme:
+ *
+ * static ssize_t show_map(struct device *dev, char *buf) {
+ * memcpy(buf, &map_seg7, sizeof(map_seg7));

+ *
+ * In general, vstusb supports standard bulk usb pipes. It supports multiple
+ * devices and multiple pipes per device.
+ *
+ * The vstusb driver supports two interfaces:
+ * 1 - ioctl SEND_PIPE/RECV_PIPE - a general bulk write/read msg
+ * interface to any pipe with timeout support;
+ * 2 - standard read/write with ioctl config - offers standard read/write
+ * interface with ioctl configured pipes and timeouts.
+ *
+ * Both interfaces can be signal from other process and will abort its i/o
+ * operation.
+ *
+ * A timeout of 0 means NO timeout. The user can still terminate the read via
+ * signal.
+ *
+ * If using multiple threads with this driver, the user should ensure that
+ * any reads, writes, or ioctls are complete before closing the device.
+ * Changing read/write timeouts or pipes takes effect on next read/write.
