I have a new USB flash drive v2.0. Why won it work in my Windows 98 computer system?
The older version v1.1 USB port will not run a newer version v2.0 USB device. However, a v1.1 USB device will work in a v2.0 USB port. I would suspect that your Windows 98 machine has the older version port installed. Note: Windows XP requires SP1 for v1.1 to work. Also, be sure to update the driver for the USB controller in Device Manager once SP1 is installed.
