Browse Source 
This patch adds support for the SuperSpeed half of USB 3.0 hubs, which
previously prevented SuperSpeed devices behind those hubs from working.

BUG=chrome-os-partner:39877
TEST=Played around with multiple hubs and devices on Oak and Falco, can
no longer find a combination that doesn't work.
