You meant high-speed USB interface, didn't you?  Full-speed is
10Mbits/sec (or is it 12?)  High-speed is the fast one.  I (and
everyone else I know) thinks the USB people were on crack when they
thought up those names.  If you really are configuring it at full speed,
there is some chance for improvement there (2x or 3x), but not 100x.
