Im using the camera ELP, i can use up to 6 cameras using a USB HUB , but I have to put an interval of 0.1 seconds between each capture, using it as follows:

fswebcam -r 3264x2448 -S 3 --no-banner --jpeg 95 -d /dev/video0 cam_01.jpeg & sleep 0.1;fswebcam -r 3264x2448 -S 3 --no-banner --jpeg 95 -d /dev/video2 cam_02.jpeg

But even using it that way, but some photos are totally dark, as if they were corrupted.
