OHCI is a standard which implments the usb stack mostly in hardware. UHCI implements it mostly in software. As such, UHCIis far more likely to have 64-bit issues. Personally I have had numerous problems with my alpha and UHCI that I was unable to track down. Try to find an OHCI. Perhaps they are more common now than when I bought my UHCI (3 years ago?). Also perhaps the UHCI stack has improved in that time...I haven't used alpha/USB in over a year.
