Power off / on all during suspend / resume
It’s very difficult to isolate what is going on. One good chance of making everything work is with 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
Housekeeping
Create the script with root powers:
sudo -H gedit /lib/systemd/system-sleep/custom-xhci_hcd
Insert text above and save file. Mark script as executable:
sudo chmod a+x /lib/systemd/system-sleep/custom-xhci_hcd
Reboot and test
If the script doesn’t help remove it with:
sudo rm -f /lib/systemd/system-sleep/custom-xhci_hcd
