From: Simon Arlott <[email protected]> Detect usb device shutdown and ignore failed urbs. This happens when the driver is unloaded or the device is unplugged. I'm not sure what other urb statuses should be ignored, and the warning message doesn't need to be shown when the module is unloaded or the device is removed.
