With U-B
Hi Ryan,
you are probably using the CONFIG_USB_OHCI_NEW option for your
PCI OHCI controller. The code in drivers/usb/usb_ohci.c is currently
not aware of caches. So we need to add some flush/invalidates at the correct
places.
I think nobody will keep you from starting to work on this :-)

Hi all,
I am porting U-Boot to a MIPS64 platform, that uses USB host controller NEC
uPD720101 on PCI bus.
I didn't modify anything related with USB driver, I just enabled OHCI in the
configuration.
When CPU cache is disabled, USB is perfect working.
When CPU cache is enabled, every driver works
