I have a Lenovo Thinkpad W510, and the following works flawlessly for
me:
1) As root/sudo, create /etc/pm/sleep.d/20_custom-xhci_hcd with the
following contents:
#!/bin/sh
# File: "/etc/pm/sleep.d/20_custom-xhci_hcd".
TMPLIST=/tmp/xhci-dev-list
case "${1}" in
hibernate|suspend)
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
;;
resume|thaw)
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
2) sudo chmod 755 /etc/pm/sleep.d/20_custom-xhci_hcd
I didn't need to create the /etc/pm/sleep.d/05_xhci file as suggested by
@Gabou, nor did I need to do anything with /etc/modprobe.d/blacklist-
xhci_hcd.conf or /etc/pm/config.d/unload_module, as suggested by
@Martin. In fact, these three files don't exist on my machine.
For other laptops that have ehci_hcd devices which cause suspend
problems, I think this script will work by simply replacing xhci_hcd
with ehci_hcd, although this isn't directly relevant to this bug report.
This works even with two usb devices plugged into the ports when I
suspend and then resume -- the devices work and don't need to be plugged
in or out.
