From: Sarah Sharp <sarah.a.sharp@xxxxxxxxxxxxxxx> Since the xHCI driver now has split USB2/USB3 roothubs, devices under each roothub can have duplicate "fake" port numbers. For the next set of patches, we need to keep track of the "real" port number that the xHCI host uses to index into the port status arrays.
