Date: Wed, 18 Dec 2013 13:10:54 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Julius Werner <jwerner@...omium.org>, Alan Stern <stern@...land.harvard.edu> Subject: [PATCH 3.10 26/78] usb: hub: Use correct reset for wedged USB3 devices that are NOTATTACHED 3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Julius Werner <jwerner@...omium.org> commit 2d51f3cd11f414c56a87dc018196b85fd50b04a4 upstream. This patch adds a check for USB_STATE_NOTATTACHED to the hub_port_warm_reset_required() workaround for ports that end up in Compliance Mode in hub_events() when trying to decide which reset function to use. Trying to call usb_reset_device() with a NOTATTACHED device will just fail and leave the port broken.
