I had mentioned couple of weeks ago that USB devices flash drives and USB mouse were not working with my Windows XP Service Pack 3 installation.

I had been looking for a solution since then and finally the problem is resolved

the USBSTOR.SYS file was missing from my Windows/System32 directory. I copied the file from another machine and placed the USBSTOR.SYS in Windows/System32 folder

After that I rebooted the computer and now the USB devices are working perfectly, I am also attaching the USBSTOR.SYS file, you can download it from here if it is missing from your system

    Thank you for your diligence, I have been pulling my hair out for 6 weeks trying to find a work-around to this USB issue in XP. AMD nor Microsoft have been able to come up with a solution.

    Best wishes and future successes,

    Gleon James
