Re: [BUGREPORT] Linux USB 3.0

[Markus Rechberger]

Seems like DH87RL was working with 3.2.0-55-generic-pae unfortunately
we don't have such a board for testing and customer patience is
limited to bisect the kernel.

Does anyone have a clue what modification could have killed USB 3.0
support within those releases?
It does not seem to be SG support.
