Windows 98 Second Edition: Updated Uhcd.sys Fixes Problem with Some USB Devices Not Running

Content

Universal Serial Bus (USB) devices that are plugged into a computer running Microsoft Windows 98 Second Edition may not work if the following hardware components are installed on the computer:

AMD processor (running at 350 MHz or faster)
VIA Technologies USB controller

This behavior occurs because there is a timing-specific problem in the Universal Host Controller driver (Uhcd.sys) that may prevent USB devices from be properly enumerated under specific timing conditions.
