4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Martin Kelly <mkelly@xxxxxxxx> commit 1cb35a33a28394fd711bb26ddf3a564f4e9d9125 upstream. Currently, when you disconnect the device, the driver infinitely resubmits all URBs, so you see: Rx URB aborted (-32) in an infinite loop. Fix this by catching -EPIPE (what we get in urb->status when the device disconnects) and not resubmitting. With this patch, I can plug and unplug many times and the driver recovers correctly.
