Problem Installing USB Mice on MY HP L2000 Laptop

I have a HP L2005CO running XP SP2. I am unable to Install Any kind of
an External Mouse. Triewd my MS Wheel Mouse & Optical USB & PS/2
Compatible that was running on my Dual Boot Dell [WinME & XP SP1]. Then
I tried A Logitech LX7 which wouldn't work so it Got retruned. We Them
Purchased a HP EW207AA Wireless but it Fails them same way as the Others
did. I get the message that says and I quote

Cannot Install this Hardware

There was a problem installing this Hardware

HID-Compliant Mouse

an Error occurred during the installation of the device

The data is Invalid

When I go to control panel and check systems/hardware/device
manager/mice and other pointing devices I see the Synaptics and an
Unknown Device. If I try to Update Driver it does the same thing.

What I need to find out is exactly what files/Drivers are being installed
I check mouse.inf from Windows/Inf. But can't figure it out
Been around the HORN several times with HP Techs but they don't seem to
be able to grasp the Problem

I'm hoping someone out there can provide some assistance.

I am thinking of Trying a "REPAIR" thinking that might replace the bad files

I haven't tried anything from the RUN Box I am nor sure if there is
Diagnostic that can be run that would point me in the right direction

TIA
