I recently purchased a Vantas 3000 USB scanner, which I am unable to use on my computer: an AMD K6-III 128 MB RAM running Windows 98.

If I plug in the scanner to the USB port, I get the blue error screen. If I restart the computer with the scanner plugged into either of the USB ports, I keep getting "Windows protection error" and thus have to start in safe mode.

However, if the scanner is not plugged in, the computer starts normailly. I have used a portable MP3 player and digital camera on the USB ports previously without a problem. Any ideas?
Any feedback will be greatly appreciated!
