I get no USB devices recognised when I insert them any more, which I think is pretty major. I suspect it has something to do with this ? > Lan Tianyu (12): > usb: add runtime pm support for usb port device > usb: add usb port auto power off mechanism It looks like every port on my laptop is powered down, as I can't even charge devices with it. I tried running powertop, which noted autosuspend for the usb controllers was 'good'. I flipped them to 'bad', but it made no difference. What can I do to debug this ? $ lspci | grep USB 00:14.0 USB controller: Intel Corporation 7 Series/C210 Series Chipset Family USB xHCI Host Controller (rev 04) 00:1a.0 USB controller: Intel Corporation 7 Series/C210 Series Chipset Family USB Enhanced Host Controller #2 (rev 04) 00:1d.0 USB controller: Intel Corporation 7 Series/C210 Series Chipset Family USB Enhanced Host Controller #1 (rev 04) $ lsusb Bus 001 Device 002: ID 8087:0024 Intel Corp.
