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.
Hi Dave: Do you disable usb port's pm_qos_no_power_off? cat /sys/bus/usb/devices/(dev)/port/power/pm_qos_no_power_off
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 ?
Can you attach the output of dmesg with CONFIG_USB_DEBUG?
