Well our current camera has a V4L based driver so we'd like to stick to that :-). > So the reason for these examples is, it is this kind of information which > one must use to judge the situation, and it is this kind of information > which one would have to provide in order to begin to get definitive > answers. This, in fact, is where one must start. Ok, to the lsusb -v info: Bus 001 Device 011: ID 0547:8031 Anchor Chips, Inc.
