The 2.0 controller doesn't _have_ increased bandwith if it's
talking to 1.1 devices.  In that case, the 2.0 controller is
transferring data at the same speed as a 1.1 controller.

A Corvette going 3MPH will get to the finish line at exactly
the same time as a 4-year-old kid on a tricycle going 3MPH.  It
doesn't matter what the controller is capable of -- it matters
what speed it's actually talking.
