I had a strange mouse problem on Ubuntu 12.10(64-Bit), the problem is that when I turnoff power supply/power goes off, the red laser light of my mouse also goes off and my mouse stops working but it works fine when A/C power supply is on.

First I thought my mouse or my laptop's USB ports had problem but since I am using Dual Boot with windows 7, I checked my mouse on windows 7 and it works fine, even I turn off power supply.

Today,I thought that I should give a try to Linux Mint 14-RC (which is based on same Ubuntu 12.10) and after installing linux mint when I plugged in my mouse it worked fine even though power is off.

Don't know what is really going on, and I am afraid if I reinstall my Ubuntu 12.10 the problem will remain.
