Hi I do not understand why I can not even get 1 image from both cameras at two different times. That indicates to me that v4l or the usb code in the kernel is not allowing the bus to be shared. I am sure that I was able to see images from two usb cameras going at one time before, but have not been able to reproduce this. One thing that I changed (I changed back but still the same problem) was XFree86 from 4.0.3 to 4.1.0. Are there any changes for v4l (or linux USB) in the future to change this? This is for a laptop, so perhaps I can find a USB port in a pcmcia card.
