It tries to catch debugfs after the controller hangs, but before the kernel "kills" it and forgets about all devices. It simply saves debugfs every few seconds, and packs the saved copy plus current debugfs and dmesg to a tgz archive when all devices disappear. Then it automatically resets the controller. Don't disconnect all devices by hand ;) The outdir and tmpdir paths need to be set to point at existing directories, and PCI ID is passed as an argument - use lspci to know if it's currently 0000:6a:00.0 or 0000:6b:00.0. I think it's somehow related to the 7-3/8-3 (USB 2.0/3.0 parts) hub, and its children - either the 7-3.4/8-3.4 hub or the 7-3.3 webcam. Would it be poss= ible to move one of those child devices to another place so that it goes to a different bus? Perhaps bus 5, which is the first 600 chipset controller, so= we could see if the problem moves to the first 600 controller or stays on the second one. --=20 You may reply to this email to add a comment.
