USB Ports don't work after Suspend

Support

As said above. Happens only after waking from suspend. Using HP Victus.

Hello @Dynamo and welcome :wink:

  1. Was it running in battery mode?
  2. Can you power up the usb ports with these commands?

Show the power status:

cat /sys/bus/usb/devices/usb*/power/control

Power up usb1 for example:

echo "on" | sudo tee /sys/bus/usb/devices/usb1/power/control

Hello!

  1. It happens regardless of that
  2. the status returns as “auto” for four usb devices. The second string does echo, but the the ports remain inactive (the 3 usb 3.0s, i don’t have anything to check the C port)
4

ok… could you run this command, for a check?
A one liner:

P=("autosuspend" "autosuspend_delay_ms" "control" "level"); for y in $(ls -d /sys/bus/usb/devices/usb*); do for x in ${P[@]}; do echo "${y:21} - $x : $(cat /sys/bus/usb/devices/${y:21}/power/${x})"; done; done

Better viewable:

P=("autosuspend" "autosuspend_delay_ms" "control" "level")
for y in $(ls -d /sys/bus/usb/devices/usb*); do 
      for x in ${P[@]}; do 
            echo "${y:21} - $x : $(cat /sys/bus/usb/devices/${y:21}/power/${x})"
      done
done

Normally TLP is responsible for suspending USB ports. You can disable autosuspending at the file /etc/tlp.conf.

USB_AUTOSUSPEND=0

However… I experience the same problem, but it did not bother me. If I really need the USB Ports again, then I just fire it up again with a custom script. At least it is more a security feature for me since nobody has access to the usb ports until I reactivate it with sudo permissions. :laughing:
