Computer mouse not detected after restart. Help!

I have taken out old USB mouse (which was detected after reboot), and plugged in new USB mouse (i ball opti smart usb mwe). When, I restart the computer (Windows XP), it is not detected. But, it does when I plug it out and again plug it in. I have to do this at every reboot.

I tried removing mouse, and after restart it is installed without any notification. It did take me plug-out and plug-out exercise though.

How should I fix this?
