YES, I have modified that with phy_to_virt for mem range for OHCI.
I can not debug UHCI, because I can not find such adapter. Amd 8111 is OHCI.

Please let me know if you can debug the code.

Regards

YH,
I have tried porting Steven's USB driver into FILO some months ago
(without success, though).
FILO is running on virtual address, but hardware that does DMA
needs to know physical address, so some translation is needed when
you pass some memory address to hardware registers.
I believe this situation is same in Etherboot.
(In fact, I stealed the idea of relocation/virtual addressing from
Etherboot.)
