USB Ports

You probably have a bad scanner, unplug all scanners. start windows, right click on my computer, properties, device manager and remove any scanners or items with ?? on them. restart windows. then plug in scanners one at a time, you should get new hardware found and the software will be found or you will install it.

As mentioned disconnect the scanner and boot up the PC. Uninstall the scanner software. There may be one of 2 issues. The first being that the softwaare has to be loaded before the scanner is connected. Secondly the scanner may need to be connected after the comupter is fully booted to Windows, there's quite a few USB devices that have to be installed this way. The scanner's software should have a readme file somewhere on the disk or a booklet that came with will explain exactly how to install.I've had so many calls on this issue because people try to install the USB devices the same as before.

1. Try using a powered USB hub between the PC and the scanner. Some devices require more power than the motherboard ports provide.

2. Try just 1 scanner at a time.
It is very possible that the scanners require mutually exclusive registry settings, or Windows files to operate.

I did solve the problem. I upgraded the port to 2.0 and reinstall Winme and the scanner worked after that.
I think it was a driver problem.
