quoted
manual, they told that this controller does not belong to
UHCI or OHCI standard.
Yes, you can call it FHCI if you like. :)
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)?
