PS/2 Mouse Problem

I currently use a PC Line USB mouse on an XP system. I need to go back to a PS/2 mouse in preparation to use a KVM, but when I plug such a mouse in it doesn't respond. The device is visible, but doesn't respond. I've uninstalled the USB mouse, but still the PS/2 mouse won't work. Strangely, after an uninstall of the USB mouse, I can plug it back in to a running system and it works ok. I can't see anything in Start Up, but could there be something running at system start up to make the USB mouse the active device ?
 
PS-2 mice are not designed to be recognized after the machine has loaded. Very few motherboard allow for that anyway.

You need to turn off the machine plug in the ps2 mouse, and the turn it on. Then the computer should detect the mouse and make it usable.

Ignorance is not necessarily Bliss, case in point:
Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.
 
Sorry, I didn't make myself clear here. I've tried booting with only the PS/2 mouse connected, but it still won't respond. It sees the mouse as a device though. At this point I can plug back the the USB mouse and that one works ok. Trouble is I need the PS/2 mouse !
 
Perhaps a long shot, but check in BIOS to see if there is an option to enable PS/2 mouse support.
 
Have you tried other mice? Maybe this one is bad, or the PS2 port on the MB has gone bad.

If you boot into safe mode, can the mouse be recognized?

If you use a bootable CD, even a Linux one can the mouse be recognized?
