IE, is the fundamental HW interface of the independent UDC operating the same way with the same register layout as one of the ports of the vHUB ? I don't like having multiple drivers for the same hardware... if it's different enough, then let's keep it separate, but if not, we should definitely split the udc from the existing vhub code so that the same driver can operate standalone or beneath a vhub.
