Do you really have any idea about USB controller ?? USB controller does not require IP address space, it uses MMIO address space which is called non-prefetchable memory in PCI spec. The controller does not need any special init stuff. I don't think USB is supported by 2.2.x kernel neither. Why do you insist using 2.2.x kernel ?

I don't want to use 2.2.x kernel,but for some reasons, I must use the version.
I don't know about USB controller indeed. But why do I see "I/O" addresses in standard bios environment on other boxes(not sis630e chipset),instead of non-prefetchable memory?
In addition,there are patches supporting USB in 2.2.x kernel.I have successfully tried it on standard bios environment with 2.2.x kernel.
Thanks, riskin
