Subject: [BUGREPORT] Linux USB 3.0

A customer using a device with USBDEVFS is reporting following
backtrace (it seems to be a rather generic issue related to linux usb
3.0 in general):
According to him this problem is reproducible as soon as he starts the
data transfer, is there anything known about that?

He is using 3.12.0-031200-generic
