We are talking about the same thing, I think. It's just that I do not
want to put the label 'UHCI compliant' on it when I have tested it with
only one chip.
Second, you need to recognise the chip to be able to apply the quirks:
PIIX4: Switch on interrupt, supports power protection, etc.
Three, from the code you would be able to derive that PIIX4 is only
mentioned in the uhc_pci.c code to print a nice string at boot time.
Four, I need alpha testers to see if, working from the UHCI spec and not
the chip spec (I only found out last sunday that the PIIX4 supports
power protection), I created something which is UHCI compliant. It is
just too early to claim that. I am not working at a marketing company
like MicroSchoft.
