looks like kernel module uvcvideo to support it in linux (auto detected and loaded in debian). I installed luvcview and luvccapture. luvcview shows the device as your typical webcam looking thing. Pretty sharp image for a webcam. And also barfs about device NOT supporting 30p. fps on the titlebar fluctuates between 25-ish and almost 40 fps.
luvcview -i 30 -s 640x480 -f MJPG -d /dev/video0
(which is what it defaults to by the looks of things)
mplayer can view the device which you can use with a named pipe to send to either mencoder or ffmpeg. I couldn't get xawtv or tvtime to work with it. Setting modes in software seem to fail miserably. It does what it does and that's it. fps seems to be off, but runs at about 30fps(+/- 10 fps). Stuck in standard def though. Which might just be linux drivers, I should probably try it out in windows.
If you're not using it as a webcam, you have to pull the USB cable which is annoying at best. And a few attempts to make adjustments made it go windows. i.e. Pull plug, pull battery, to recover / regain usability.
