Is this on a DevBoard ? If so, note that your USB cam will show up as camera 1 not camera 0. Do if you're using gstreamer, set the source to /dev/video1 , if you;re using pygame, change the camera line to pygame.camera.Camera(camlist[1], ...

But it works with a different camera ? Check your camera's capabilities using v4l2: v4l2-ctl --list-formats-ext -d /dev/video1
