SmartDisk FireLite USB not detected

I have a Windows 98SE system with a Belkin USB PCI card installed. USB working great and able to detect and utilize HDs installed in portable USB cases. Acquired SmartDisk Firelite USB, installed Windows 98SE drivers, plugged in FireLite…. device detected and appeared to install drivers….. no drive appears in My Computer…. nothing in Device Manager. No problems shown in Device Manager. What do I do now??? Any ideas???
