You know, given my druthers we'd have the HCD registration
check this, rather than updating every HCD's setup logic...

Care to try a maximally generic fix instead? :)

Sorry, I don't have the time to figure out how that works.
This one seemed to be the only one missing the test of
usb_disabled() anyway (I copied the code from one of
the other ones.)
