1. Install an USB PCI card. Around here, 10 bucks or so.
2. Read http://www.usbman.com for clues.
I am posting this for my sister who cannot get online due to a problem with her USB port and a cable modem. She has a Win 98 computer with one USB port. After a recent move, the USB is now not working - it was before the move. The problem was discovered when they tried to hook up the USB cable modem and the USB would not work. It looks okay in the device manager, but there seems to be no power to the USB.
I am sorry that I can't give you the system details since it isn't my system. It is a Dell running Win 98 SE I believe. It is about 5 years old, so it is probably a first generation of USB ports - but it was working until the computer was moved.
Could there be a loose connection or a simple explanation of how to fix this. Any help you can offer is appreciated.
