I heard that on the PQII (82xx) devices the FHCI required
intervention from the core, even when there was zero traffic
on the USB.  I think this was because the core had to
continuously service a 1ms interrupt.  This generates significant
extra loading, making it worth considering using a cheap EHCI chip
instead....

Does anyone know if this is still the case with the PQII Pro (83xx)?
