We have rewritten the brlvger (Tieman Voyager USB Braille display) driver
so that it works from user-space through usbfs. It appears to work just as
well as the in-kernel driver.

The brlvger driver in the 2.6.x kernel is now obsolete and should be
removed. The attached patch against 2.6.3 does this. Please apply.
NB: The following files are completely deleted:
    Documentation/usb/brlvger.txt
    drivers/usb/misc/brlvger.c
    include/linux/brlvger.h

The new Voyager driver is available (stil under GPL) as part of BRLTTY,
starting with version 3.5pre1 (http://mielke.cc/brltty).
Thanks to Dave Mielke who implemented BRLTTY's usbfs functionality, among
lots of other stuff.
