+USB 7-Segment Numeric Display
+Manufactured by Delcom Engineering
+
+Device Information
+------------------
+USB VENDOR_ID   0x0fc5
+USB PRODUCT_ID  0x1227
+Both the 6 character and 8 character displays have PRODUCT_ID,
+and according to Delcom Engineering no queryable information
+can be obtained from the device to tell them apart.
+
+Device Modes
+------------
+By default, the driver assumes the display is only 6 characters
+The mode for 6 characters is:
+        MSB 0x06; LSB 0x3f
+For the 8 character display:
+        MSB 0x08; LSB 0xff
+The device can accept "text" either in raw, hex, or ascii textmode.
+raw controls each segment manually,
+hex expects a value between 0-15 per character,
+ascii expects a value between '0'-'9' and 'A'-'F'.
+The default is ascii.
+
+Device Operation
+----------------
+1.      Turn on the device:
+        echo 1 > /sys/bus/usb/.../powered
+2.      Set the device's mode:
+        echo $mode_msb > /sys/bus/usb/.../mode_msb
+        echo $mode_lsb > /sys/bus/usb/.../mode_lsb
+3.      Set the textmode:
+        echo $textmode > /sys/bus/usb/.../textmode
+4.      set the text (for example):
+        echo "123ABC" > /sys/bus/usb/.../text (ascii)
+        echo "A1B2" > /sys/bus/usb/.../text (ascii)
+        echo -ne "\x01\x02\x03" > /sys/bus/usb/.../text (hex)

           The Serial Gadget talks to the Linux-USB generic serial driver.
           This driver supports a CDC-ACM module option, which can be used
           to interoperate with MS-Windows hosts or with the Linux-USB
           "cdc-acm" driver.
 
+          This driver also supports a CDC-OBEX option.  You will need a
+          user space OBEX server talking to /dev/ttyGS*, since the kernel
+          itself doesn't implement the OBEX protocol.
+
           Say "y" to link the driver statically, or "m" to build a
           dynamically linked module called "g_serial".
 
           For more information, see Documentation/usb/gadget_serial.txt
           which includes instructions and a "driver info file" needed to
-          make MS-Windows work with this driver.
+          make MS-Windows work with CDC ACM.

+ *  The vstusb module is a standard usb 'client' driver running on top of the
+ *  standard usb host controller stack.
+ *
+ *  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.
