The problem seems to begin when all = the USB devices connected to that controller disappear during the second system resume and never show up again. I suggest you send an email describing the problem (include a pointer to th= is Bugzilla entry) to the linux-usb@vger.kernel.org mailing list and CC: the x= HCI maintainer: Mathias Nyman . He'll probably have s= ome requests for more tests you can run. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
