Comment 61 for bug 522998

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.
