I discovered that a colleague had unplugged the power lead from my
laptop (it was running on battery), so I think that means it's an
identical bug to
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1060029 so I'll
mark as duplicate. However, this is important as it's a different
machine and OS build altogether. Will check with a mainline kernel.

Title:
External USB trackball and keyboard become unresponsive when not used
Status in “xorg” package in Ubuntu:
New
Bug description:
I'm running a laptop with the attached (powertop) interventions to
improve power-saving behaviour. Having used Ubuntu Gnome Saucy for
some time with xorg-edgers, I decided to roll back to xswat for
stability reasons (was getting crashes when playing flash/Youtube
within Chromium).
However, after several hours of use, I found that the trackball and
keyboard are now non-functional when events weren't detected from them
for 10 seconds or so, although continuous use keeps the device working
just like https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1060029
After the device has suspended, generating a click event (on the
trackball) or a key event (on the keyboard) causes the device to come
back to life, but the event is consumed (ignored) meaning, for example
if you want to type something, you can expect initial characters not
to appear. Moving the trackball alone doesn't bring the trackball back
online, only a click.
This seems an intermittent issue, as the device was working fine for a
long time during this boot session. I'll first try rebooting with the
xswat drivers, and then roll back to the ubuntu repo for testing.
For reference, running the attached script which reverses the
conservative power configuration doesn't resolve the issue, even
though it seems to modify the /sys/bus values correctly.
