Mouse USB not working on windows xp - error code 41

Hi, I'm facing a terrible problem with WinXP Pro.
After I removed a software, all my usb ports stopped working.
After a night of reinstalling and upgrading, I got USB to work for everything but ..the mouse!
If I upgrade the driver and I always got this message:
"Driver loaded.It is impossible to find the device. Code 41"
Any clues?
Thanks in advance

Try the following...

in right page double click on on upperfilters (data->Kbdclass) and in the value data it should contain kbdclass only and one enter so the cursor chould blink on the next line on the value. Then click on OK and exit the registry editor, and restart the computer and then try to use the keyboard

What type of system is this, it the system has intel chipsets, then download the drivers from Intel for any Motherboard website directly rather than PC/ system vendor website. I have came across this on specifically Dell systems where if you download the Chipset drivers from dell website devices such as bluetooth, USB ports, video won't work or not even install,

best of this would be go to www.driveragent.com run a free scan on the system and it will tell you exactly what drivers are needed then google those drivers and download them from Mother Board vendor website,
other things would include checking different ports, test the components on another system and make sure they work,

hope this helps.

Reset bios to default first see if it helps. If not, try other mouse see if problem is same?
Also, here are some possible USB solutions:

Remove all USB drivers with:
, let it reinstall them, delete the "UpperFilters" and "LowerFilters" registry values from:
, check:
and the "SIMILAR PROBLEMS AND SOLUTIONS" section, and run:
rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 C:\WINDOWS\inf\usbstor.inf

If you still find the above are not working...

try reinstalling windows xp which will replace only system files.

options to chosse while reinstallling... Press enter to install windows xp (dont go to repairing console) and select install on the existing version of windows xp option.

I think this will be the  only solution, if the above are not working...

all the best...
