This cleans up a great deal of flakiness that we've seen on the USB for a long time. I was misinterpreting and/or misimplementing some of the documentation. This seems to make all the difference. BUG=chrome-os-partner:50370 BRANCH=none CQ-DEPEND=CL:328979,CL:*249229 TEST=make buildall, and test on Cr50 Before this CL, the USB connection would only work on USB2.0 buses, connected directly to my workstation. With this CL, it works on USB2.0, USB3.0, through hubs, etc. Yay!
