Hi, I tried to use a stereo USB webcam (that works correctly under other OS's) with OpenCV, using Snow Leopard's QTKit. I could list the 2 cameras but always produced a crashe when trying to get image data from the second. Googling for it, I found some info saying that you can't have 2 cameras on the same USB bus.
If this info is correct, then you may be stuck in the same dead end.
