Title:
  [Lenovo ThinkPad X230 Tablet] USB devices in docking station no longer
  working after resuming from long standby

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Please see:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1116525

  When my Lenovo Thinkpad x230t is attached to an Ultrabase Series 3
  dock and suspended for many hours. Upon resume the USB ports on the
  dock, but not the laptop, stop working with peripherals (mouse,
  keyboard, usb drive). Shorter periods of standby seem unaffected
  unless the issues has already occurred. E.g. After a fresh boot if I
  suspend my laptop and resume after less than about 8 hours (I am not
  at all certain if the period of time is related. Just general
  observation), everything will continue to work fine. If however the
  issue has occurred at some point and I have disconnected and
  reconnected to work around the issue, and then I suspend for a short
  period of time (20 seconds) and resume, the dock's USB ports will no
  longer work unless I again disconnect the laptop from the dock and
  reconnect. So it seems once the issue has happened it will continue to
  happen until I reboot.
