Not good. This fails when an xHCI controller is removed.
but the user had a xhci controller during the life time of the system.
Then you would not print this message unless we have such a controller.
This could be extended to usb2 in 1.1 port but I guess this is no longer
required :)
You don't have to be so complicated about it. Just copy the logic
used for highspeed_hubs in hub.c.
Actually, the more I look around it the better it looks.
