I guess that's why there is no explicit mention of USB 3.0?

But then, why is xhci there?  Placeholder for future improvements?

A USB 3.0 device in a USB 2.0 port, or a USB 2.0 device in a USB 3.0 port, gets 
USB 2.0 speed.

But the only testing I did in that regard with NetBSD was Western Digital USB 
3.0 MyBook Essential hard drive in USB 2.0 ports: some worked, some didn't.
