Here is the script which should reverse the 'power-saving' interventions, but has no effect on the bug.

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.
