Skeleton driver for the LG GP40NW10 USB DVD writer [O. Galibert]
It is (was?) an inexpensive dvd writer. I started this driver to see if it was possible to add commands for really raw reading. Let's just say that mcs51 code is a pain to read. If it ever works, it can be interesting as a USB device for when we end up insane enough to try to handle USB in the first place.
