Same for UHCI spec. Be aware of the fact though that without support for
separate chipsets you will not be able to figure out the way to do it
according to the specs.

The final result should be according to [OU]HCI spec and chipset
independent, I agree, but for the moment we do not have the knowledge
nor the base to claim that it is chipset independent.
