huh.  okay, well, 1.75 is the first of the XO models that has the
ability to leave the USB ports powered (and i assume they all do when
the mobile dongle is used - the hardware control is all or none).  i
guess that driver is talking to the USB stack somehow to accomplish
this.

next question:  is this the right behavior?  if the dongle weren't
power cycled during resume, i guess that might be a good thing?
