Power off USB devices when suspending
My suspend/resume broke about a year ago. The solution for me was powering off the USB devices before going to sleep and powering them on with resume.
In the directory /lib/systemd/system-sleep create this script:
#!/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
Mark the script executable with chmod a+x /lib/systemd/system-sleep/custom-xhci_hcd
Reboot.
Confirm script is working with journalctl -b-0 | grep custom-xhci_hcd:
