[Bug 1388072] Re: [Lenovo ThinkPad X230 Tablet] USB devices in docking station no longer working after resuming from long standby
I'm afraid I did not have the dock prior to Trusty so I have no
experience with any earlier versions of Ubuntu.
** Changed in: linux (Ubuntu)

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:
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.
