Comment 23 for bug 1091014

I forgot to mentioned an important detail about the nature of this bug. Often if I remove the power cable (the adapter cable) it is able to detect the touchpad, then after boot is completed I put the adapter cable in and most if not all the subsequent boots with the power cable inserted the kernel detects the touchpad.
If I shutdown and change room, insert the adapter cable into another socket and boot, the touchpad is not detected. It seems to have something to do with the presence of the adapter during boot interfering with the bus.
Saying that I don't think it's a hardware failure because the Windows partition manages to initialise the touchpad independently on whether the power cable is attached or not. Now my battery is flat and cannot boot without power cable.
