Title:
  Enabling wakeup on the USB Root Controller prevents computer from
  suspending

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Steps to reproduce:
  1) As root: # echo enabled > /sys/bus/usb/devices/2-1/power/wakeup
  2) Attempt to suspend computer.

  Expected results:
  Computer should suspend.

  Observed results
  Computer goes into suspend then immediately wakes up. There is nothing informative in /var/log/pm-suspend.log

  Background:
  This bug was discovered by a udev script that I wrote to allow waking my computer up from suspension by attached USB devices. This is the script:
  ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="15d9", ATTRS{idProduct}=="0a4d" RUN+="/bin/sh -c 'echo enabled > /sys$env{DEVPATH}/../power/wakeup'"

  A recent regression meant that this now prevents the computer from
  suspending as above. This script now writes "enabled" to both
  /sys/bus/usb/devices/2-1/power/wakeup and
  /sys/bus/usb/devices/2-1/2-1.1/power/wakeup . I'm not sure if the
  regression was that it now writes to the former as well as the latter,
  or if it always has written to both, and a regression in pm-suspend
  now cannot deal with the former. If I write "disabled" to the former,
  I can suspend as normal.
