Out of the blue, perhaps with a kernel update, the driver stopped working in
Kopete, mplayer, and xawtv. Kopete and mplayer show a green screen. Xawtv
just shows a black screen. Luvcview has never worked for it, and still
doesn't. I'm at a total loss of what to suggest... a whole bunch of output
is below:
