Comment 4 for bug 800110

Things seem to be getting worse. Now after a clean reboot, my external USB keyboard and mouse send events to X only after I've called lsusb from the console, and only then for a short while.

After about 10 seconds, my mouse disappears once again, and lsusb needs to be called again in order to redetect it, after which it works again for about 10 seconds before dying again and so on.

As long as the mouse continues sending events (I roll the trackball around) it stays connected. The moment it is idle again, it's permanently disconnected until another lsusb. This is also now under the generic natty kernel.

My builtin keyboard and mouse work throughout.

I'll see if I can eliminate some kind of physical issue with the mouse when I get hold of another one. As for physical issues with the laptop, I don't know what I can check to ensure that the USB subsystem isn't actually disappearing and then reappearing on the bus because of some wiring issue, but the fact it stays connected while sending events, suggests to me that it's software.

Is there anything I can do to force the reconfiguration of the usb subsystem or kernel modules, beyond reverting to the natty 2.6.38-8 kernel, which I've already done. Something in my build needs a good kick.
