Message-ID: <CA+O4pCJ5xUQwRem3rvZbvv7K8BEnMW983Qq_vR0tVzwAwmVS6A@mail.gmail.com> Date: Fri, 27 Dec 2013 20:59:37 +0100 From: Markus Rechberger <mrechberger@...il.com> To: LKML <linux-kernel@...r.kernel.org>, USB list <linux-usb@...r.kernel.org> Subject: Re: [BUGREPORT] Linux USB 3.0 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.
