Not to add to the pile, but my Thinkpad X1 Carbon's USB ports (which
all support 3.0) don't work with some USB2 devices either.  I plug the
modem in, and nothing happens.  I move the modem to a USB port on
another device, and it's recognized fine.  Happens with my USB -> mini
PCI-E or USB -> M.2 adapters and some Sierra devices IIRC.
