The LED light of my mouse gets on my nerves when sleeping. I usually close my notebook in the evening and Ubuntu calls pm-suspend. Anyways, the USB plug is still served with power. I could even charge my smartphone. This is bad for me for two reasons. I have to unplug my mouse and the notebook battery pack [akku] lasts less. Is there a way to automatically power off my USB device, or all USB devices, when the notebook goes into suspend mode?

How to configure it?

EDIT: As requested in the comments, I add this information: I am using a Lenovo G550.

    I don't think this sleep charge feature is something to do with Ubuntu. Windows and Ubuntu do it for me on my laptop. Instead, there should be a setting in BIOS to turn off power to the USB ports during sleep. – TheWanderer Sep 10 '16 at 13:52

    Are you sure? Google showed me some information for the keyword "usb suspend ubuntu". But I am not yet 100% sure how to do it right. hamwaves.com/usb.autosuspend/en askubuntu.com/questions/80638/… – tokam Sep 10 '16 at 14:19

    Well you can disable them, but that's while Ubuntu itself is running. If you want to make scripts to run before the laptop sleeps to suspend the ports, it's possible, but it's going to be easier to at least check your BIOS settings for that option. – TheWanderer Sep 10 '16 at 14:21

    My BIOS unfortunately does not support such an option. – tokam Sep 12 '16 at 10:05

    @tokam, could you edit question and add the brand and model of the laptop? Also could you confirm that it is not a USB power-share port as explained here: dell.com/support/article/ro/ro/robsdt1/SLN155147/EN (lightning bolt icon) – user.dz Sep 27 '16 at 10:53

The current stumbling block with OP links, follow up comments and proposed answers is the product ID is static 1b1a:7001 but the Bus and Device numbers keep changing.

The solution

Create a script (any name you want) in the directory /etc/pm/sleep.d/ and place the following in it:

#!/bin/bash
ZeroBUS=$(lsusb | grep 1b1a:7001 | cut -c  5-7 )

# Strip leading zeros
BUS=$(echo $ZeroBUS | sed 's/^0*//')

# Build "usbX" usb number
USB=usb$BUS

case $1 in
     suspend|suspend_hybrid|hibernate)
     echo "Powering off: " $USB
        echo $USB | sudo tee /sys/bus/usb/drivers/usb/unbind
        ;;
     resume|thaw)
        # No need to do anything here, kernel unsuspends USB devices
        # Show how to power on for interest sake but since device is
        # powered off the usb number will be blank.
        echo "Powering on: " $USB
        echo $USB | sudo tee /sys/bus/usb/drivers/usb/bind
        ;;
esac

Mark the file as executable with sudo chmod +x file_name where "file_name" is the name you chose.

The explanation

This solution powers off the entire USB hub which in my case meant phone, wireless mouse, wireless keyboard, etc. When calling the script from terminal prompt the sudo password needs to be entered. Hopefully when called from systemd sudo powers are inherited. I could not test this though because I don't have a wired mouse. Therefore additional refinement may be necessary for sudo powers.

The power isn't physically cut when the BIOS is providing constant 5V power supply, rather the devices on the bus are told to turn themselves off. In my case the wireless keyboard and mouse stopped working and had to resort to laptop keyboard and touchpad to return power back on.

You can test this manually by calling the script and passing the parameters "suspend". Passing the parameter "resume" accomplishes nothing because the device is powered off it has no device ID to turn it back on.


Easier solution power off all USB ports

I recently ran into a problem where an unknown port was preventing laptop from suspending. I found this solution (credit in code) which I modified.

Create the file /lib/systemd/system-sleep/custom-xhci_hcd using sudo powers and insert this code:

#!/bin/bash

# Original script was using /bin/sh but shellcheck reporting warnings.

# NAME: custom-xhci_hcd
# PATH: /lib/systemd/system-sleep
# CALL: Called from SystemD automatically
# DESC: Suspend broken for USB3.0 as of Oct 25/2018 various kernels all at once

# DATE: Oct 28 2018.

# NOTE: From comment #61 at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/522998

TMPLIST=/tmp/xhci-dev-list

# Original script was: case "${1}" in hibernate|suspend)

case $1/$2 in
  pre/*)
    echo "$0: Going to $2..."
    echo -n '' > $TMPLIST
          for i in `ls /sys/bus/pci/drivers/xhci_hcd/ | egrep '[0-9a-z]+\:[0-9a-z]+\:.*$'`; do
              # Unbind xhci_hcd for first device XXXX:XX:XX.X:
               echo -n "$i" | tee /sys/bus/pci/drivers/xhci_hcd/unbind
           echo "$i" >> $TMPLIST
          done
        ;;
  post/*)
    echo "$0: Waking up from $2..."
    for i in `cat $TMPLIST`; do
              # Bind xhci_hcd for first device XXXX:XX:XX.X:
              echo -n "$i" | tee /sys/bus/pci/drivers/xhci_hcd/bind
    done
    rm $TMPLIST
        ;;
esac
  • Can I test the script somehow before actually suspending the notebook with an non dynamic echo command? – tokam Oct 16 '16 at 7:41
  • you were able to successfully isolate the bus and device which is also shown in lsusb, but as you pointed out the directory does not exist, as shown in the question, the directories have a different structure than ${BUS}-${DEVICE}, and I am not sure if even with knowing which one is the right one the suspending works – tokam Oct 16 '16 at 7:43
  • A test in which I unplugged and replugged the mouse helped to identify the folder. But look at the output of the next test: Keine Berechtigung means: no permission root@localhost:~# echo suspend > /sys/bus/usb/devices/2-5.1.2:1.1/power/level -bash: /sys/bus/usb/devices/2-5.1.2:1.1/power/level: Keine Berechtigung – tokam Oct 16 '16 at 7:47
  • The mouse has an LED at thouse outside and a laser at the bottom. With a combination of both answers provided, I was able to turn the laser of the mouse off, but not the LED, which adds light no my sleeping environment. Maybe we can not turn the LED off by the Kernel? I tested it on an isolated USB Plug for the mouse. – tokam Oct 16 '16 at 7:58
  • @tokam After a lot of research and testing I finally got it to work on my system manually but do not have your mouse to test it. Hopefully it works! – WinEunuuchs2Unix Oct 16 '16 at 13:57

Find the bus and device # of your mouse by issuing the command lsusb (with and without it plugged in) you want the one that's only there when it's plugged in. Make a note of the numbers. In your case they appear to be 6 and 6

issue the command sudo cp /etc/pm/sleep.d/novatel_3g_suspend /etc/pm/sleep.d/mouse_suspend (we have to do this because gedit no longer has a Save As option when launched as superuser that I can find.)

issue the command gksu gedit /etc/pm/sleep.d/mouse_suspend Change the Bus and Device numbers to match the ones you took note of earlier. Save the resulting file. It will be executed when you suspend your laptop.

In your case you should change BUS=X and DEVICE=Y to the Bus and Device numbers that match the mouse in question. This will work until you move the device to a different port in which case you will have to locate the device again and adjust the file accordingly.

BUS=X
DEVICE=Y

if [ ! -x /sys/bus/usb/devices/${BUS}-${DEVICE}/power/level ]; then
    exit 0
fi

case $1 in
     suspend|suspend_hybrid|hibernate)
    echo suspend > /sys/bus/usb/devices/${BUS}-${DEVICE}/power/level
        ;;
     resume|thaw)
    # No need to do anything here, kernel unsuspends USB devices
    :
        ;;
esac

The comments in the file (lines beginning with #) are irrelevant and can be safely ignored.

Note: I tested this via Suspend on a desktop and it worked as advertised. I do not have access to the same hardware you have but I had to resume the system via the power button so I'm fairly certain this will work for you.

Edit based on comments and expansion of question:

It appears that this is the info you need to proceed: Bus 006 Device 006: ID 046d:c52b Logitech, Inc. Unifying Receiver

  • In my gedit Ubuntu 16.04 vanilla upgrade from 14.04 there is a Save as option under the File menu. Something must have happened to your configuration??? PS good answer, I'll try it later. – WinEunuuchs2Unix Sep 28 '16 at 11:44
  • I have file save as too, using Ubuntu Mate. – tokam Sep 29 '16 at 10:34
  • @WinEunuuchs2Unix Interesting. It doesn't appear to exist on a fresh install. Perhaps this is the basis for a new question.... – Elder Geek Sep 29 '16 at 14:26
  • @ElderGeek An update on Save As if I type gedit I get the entire top line menu of "File Edit View Search Tools Documents Help" but if I type gksu gedit the menu list doesn't appear. HTH. – WinEunuuchs2Unix Oct 1 '16 at 17:22

    @tokam Can you update your question with output from lsusb -t and lsusb with all your devices plugged in as you normally use them day-to-day. That might help us visualize the hub and what not. – WinEunuuchs2Unix Oct 4 '16 at 23:05
