Maintainer of usb code

[Luoqi Chen]

Hello,

Do we have an official maintainer of the usb code? I came across some quite trivial
errors while debugging another problem (which turned out not to be usb related),
please see the diff below. I'm not terribly familiar with the usb code, so I'd like
to seek someone to review this change,
