Hi I have a setup on my computer where two different brands of webcams upload to the web at 5 second intervals. Randomly, these cams seem to "switch." IE the picture from camera 1 ends up on camera 2, and the image from camera 2 ends up on camera 1 - sometimes one camera takes over both. Any idea what is causing this or how to solve it? They also are on seperate USB cards (have two PCI USB cards installed for a total of 4 ports). Any help would be much appreciated!
