I have seen USB working under BE mode in many instances. (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.
