Message:

xhci: port speed detected properly

The correct way to determine protocol supported on a port is to look at the Port Speed value in the port register, and use it as an index to the speeds defined in extended capabilities. Now we support non-contiguous ranges of ports, USB 3.1, and the detection would work even for non-USB protocols.
