Hi Mathias, regarding commit f161ead70fa6a62e432dff6e9dab8e3cfbeabea6 Author: Mathias Nyman <mathias.nyman@xxxxxxxxxxxxxxx> Date: Fri Jan 9 17:18:28 2015 +0200 xhci: Check if slot is already in default state before moving it there you are marking this for stable only on 3.14+ I don't see why. Yes, the new scheme makes hitting this problem easier, but as it is a limitation of the hardware it should exist in all versions of the xhci driver. I am confused. Could you elaborate?
