There is a timing issue with the Universal Host Controller driver (UHCD.SYS) supplied with Windows 98SE. USB devices under Windows 98 Second Edition may not work if either an AMD processor (350 MHz or faster), or a VIA Technologies USB controller are installed. The issue is corrected in later versions of Windows (Millennium Edition, 2000, XP).
USB 2.0 devices are considered new technology. Testing among component vendors is ongoing as new USB devices and drivers are updated. For best results, we recommend you upgrade the operating system to later versions of Windows: ME, 2000, or XP. USB 2.0 driver support is more robust in later releases.
