Hello, I have some win98se computers i have installed "UNOFFICIAL Windows98 Second Edition Service Pack 1.6.2 (Freeware)" on and indeed it did add plug and play USB support. I have had a couple instances where i have plugged a usb memory stick in and it picks it up and says it installs the drivers etc. but when i go into my computer it doesn't show the drive. With other drives it goes through the exact same procedure and works just fine. An example of a problem drive would be IOMEGA mini Drive 128mb. Any input is greatly apriciated! Shamrock
