I thought the total bandwidth available for a controller was different than the bandwidth at which it communicates with one device. You're saying any 1.1 device that uses 12 mbit/s will 100% monopolize a 2.0 controller so no other devices can function? Taking a different approach, since I have 2 USB controllers (EHCIx1, OHCIx1) why can't I operate one webcam on one controller and one webcam on the other controller so they can both function? - Grant >> I get the feeling I have a misconception somewhere along the >> line here.
