Ps2 mouse in XP Pro

Friend just wiped his HP clean and installed XP Pro. Ps2 mouse was working fine. Put in the SP2 disc and when it got finished, the Ps2 mouse would not work. Plugged in a USB and all is fine. Did all the windows updates and still the same problem. What does he need to check to see why the Ps2 mouse quit? He was going to wipe it again and start over to see if the port had gone bad. Told him let me check here first. The mouse is good as switched PC's with the same type. Has the USB to Ps2 adapter. Device Manager is fine. He took a mouse, (same type) and switched them. Same results. Both are good. The mouse in the PC in question that is working as a USB shows that it is HID Compliant Mouse. Told him to give me till tomorrow before a reinstall. May have him do a sfc /scannow or Repair as this may or may not work and is quicker then a clean install and all the updates. This was not a slip stream install. Did the XP disk then immediatly did the SP2 disk. He has done this before and so have I with the same type of mouse and never had this problem. He did this 2 times before on the same PC and it worked fine. The HD was zero wiped with a Floppy disc. Then the install went after that.

 

PS2 Mouse

Though it display HID Compatible i suggest you to remove all USB Drivers from HARDWARE Manager ,plug in your USB PS2 Mouse and then Reboot your system .

Thanks for the suggestion. Just ran over there and for the heck of it, I uninstalled it from the Device Manager and of course did a hard shutdown and pluged it into the Ps2 Port, rebooted and all is fine. Don't know why I/we didn't think of that as lots of times that will fix problems.
