I have Dell Venue transformer with LUbuntu 18.04 with the kernel 5.1.0-6.4-liquorix-amd64 #1 ZEN SMP PREEMPT liquorix 5.1-4ubuntu1~bionic (2019-06-03) x86_64 x86_64 x86_64 GNU/Linux. I disabled wakeup by all devices except PBTN. In BIOS USB PowerShare is switched off.

Nevertheless, after suspending the laptop remains warm. Only three devices do not change the power state:

$ cat /proc/acpi/wakeup
...
EHC1      S0    *disabled
EHC2      S0    *disabled
XHC   S0    *disabled  pci:0000:00:14.0

Testing by non-controlled USB LED toys shows that they are remain on during suspend. Installing laptop-mode-tools is not helpful (possibly, some additional settings are necessary).

How to set the devices to S3 or S4 state?

I had a similar problem recently when all of a sudden suspend stopped working due to USB. I wrote this script to fix it:

#!/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

Place the script in /lib/systemd/system-sleep/custom-xhci_hcd and mark it executable with:

chmod a+x /lib/systemd/system-sleep/custom-xhci_hcd

On next reboot script is activated.


Suspend message log

Use journalctl -xe and press Page Up numerous times to see the suspend messages:

  • The folder "system-sleep" has been created in "/etc/systemd/". The script has been copied and marked as executable. After restart the power state remains S0. – v_mil Jun 13 at 19:12
  • Sorry typo. Folder already exists as /lib/systemd/system-sleep. Copy the script there to make it work. – WinEunuuchs2Unix Jun 13 at 19:32
  • I moved the script to the correct folder and restarted. The power state remained S0. When the lid was closed, all USB peripherals (Ethernet, wired mouse) remained on (the mouse LED did not switch off, the "Data" LED on the Ethernet controller continued blinking). After waking up, all peripherals switched off and on. The mouse stoped responding until manual re-plug. I moved the script outside the target folder and restarted. After closing the lid, the peripherals now operate normally except S0 state of the host controllers. – v_mil Jun 14 at 15:39
  • Something may have changed in kernel after October 2018. I will check system logs for errors. Thanks. – WinEunuuchs2Unix Jun 14 at 17:07
  • Also what does /etc/systemd/logind.conf contain for two LidSwitch entries? – WinEunuuchs2Unix Jun 14 at 17:14
