mem_base=0 is bad. It is followed by ohci->regs=mem_base.
In SA1111 it is USB_OHCI_OPBASE.

Have you reserved the lowest 2MB for DMA like SA1111 does it ?
Have you enabled DMA in TUCR ? The resource handling

What device is that ?
My /usr/share/usb.ids says Prolific technology PL2301
USB-USB bridge.

PS. You are very brave person to deal with the 2.4 SA USB code :)
