Oh sorry my bad, i assumed it was running XP.

Does your friend have a Windows 98 CD? If so go into the Device Manager right click on the USB device and click properties, and then click on the Driver Tab and then click Update Driver. Click Next on the first screen and then choose the option (Install from a specific Location). Uncheck Search in these locations, and then check the box that says (Include this location in the search) and then click browse, and select the CD Rom drive and click Next.
