Windows 98/95 OSR2 Problems and Solutions
Problem:
Your computer does not recognize your USB scanner.
USB support must be installed and enabled or the scanner will not
work. Different USB chipsets have different levels of USB
compliance. The initial USB chipset that was released was the
INTEL82371SB. It supports most low draw devices such as mice
and joysticks, but high draw devices such as scanners might have
trouble functioning on the “SB” chipset.
Later chipset versions include SIS, ALI, and both have many fully
functional chipsets as well as Intel’s 82371AB and 82371AB/EB.
Solution:
To determine your USB chipset type:
1. Click the My Computer icon using the right mouse button. A
pop-up menu appears.
2. Click on Properties command using the left mouse button. This
brings up the Device Manager.
3. The last item listed in the Device Manager should be Universal
Serial Bus Controllers.
4. Click the + beside the Universal Serial Bus Controllers entry.
Two items display, (your chipset) PCI to USB Open Host
Controller and Root Hub.
