(Acutally that I have two that work.). I don't think endianess is the issue. I have seen "number assign failures" a couple of times before, and it is all because interrupt not routed correctedly. That is where "more than likely" comes from. Of course, I have only dealt with PCI USB controllers. On-chip ones may have another set of additional issues that I am not aware of. Jun
