Interesting!

 Hopefully, we can use this to test the patch to Eric and Matt's
 satisfaction. Their concerns center around moving a USRP between
 USB1.1 and USB2.0 hosts. I'm attaching the patch just in case anyone
 else would like to play with it.

Philip, the patch will need to handle to handle the cases where the
USRP is already powered up and then is plugged into a 1.1 port, and
later into a 2.0 port, and vice versa.  I suspect that taking a look
at the Cypress library source will provide a clue as to how to
proceed.  IIRC, there's an interrupt than can be enabled, that will
tell you when the speed changes.  It might be called something like
HSfoo or some such.
