Although USB is in the title, 3.0 was enough different than its predecessors
that I have found it problematic, in certain scenarios, in almost all the OS's
I have tried.  The xHCI specification may be "one USB to rule them all",
but sometimes it seems that that may have been one (USB) bridge too far.
It has gotten much better, and I am sure it will continue to improve, but
I still occasionally encounter edge cases.  There was even a recent post
about the linux kernel xHCI driver not waiting long enough for devices to
come out of sleep resulting in device disconnects.
