I'm looking at the box of one of the webcams and it says "USB 2.0 compatible". It's not a cable problem because the cable is built right into the webcam. I'm not trying to get the webcam to go faster back and forth to the controller, I just need to make sure I don't have both webcams on the same OHCI (1.1) USB controller. I would think buying a USB expansion card would work, but I have an EHCI (2.0) controller on this system and a second OHCI (1.1) controller. Does anyone have any idea on this. It really doesn't make sense. - Grant
