This executable installs all necessary generic drivers to utilize USB Flash Drives. In my case, I couldn't find any suitable Windows 98SE drivers for the PNY Attache' 2.0G Flash Drive, and I contacted www.usb.org technical support and was given a link for this .exe to run. Instructions are to uninstall all USB drivers, all unknown devices, and all USB 2.0 drivers, then run the executable, which then installs the necessary USB contollers and the generic USB storage device driver. THIS WORKED ON THE FIRST TRY!!! EXCELLENT!!! I recommend it for anyone who has had issues installing appropriate USB storage devices with Windows 98SE , and especially anyone with a PNY Attache' 2.0G USB Flash Drive. WHAT A GODSEND!!
