Ubuntu not detecting USB mouse

[Sherin George]

Hello,

I have ubuntu karmic koala installed in my PC.

Recently, I purchased a new USB mouse. My ubuntu is not detecting
this USB mouse on boot. Still, it will detect my USB my mouse if I
unplug it and plug it again when linux is booted.

Could some one please help me to find what is wrong or how to troubleshoot.

Thanks in advance.
