I've just got my hands on Videosmart VX-3001 medical video-grabber. It
seems it has some common hardware under the hood, but I only managed
to get dark-green screen in Cheese.  I include some of my specs,
dmesg and lsub. Being completely green in driver development I'd like
to get some help in figuring out  how to make it work.
