O.K.

My uncle wanted me to setup a scanner (Visioneer 5800 OneTouch USB) he bought last week. And I thought this was going to be a piece of cake...was I wrong....

After the first reboot after software install, the scanner is recognized. But when you shutdown and power back up. The scanner is seen as an "Unkown Device" under "USB Controllers" in Device Manager. If I unplug it, delete the "Unkown Device" and plug it back in, it's still seen as "Unkown Device". The only way to have the computer see the scanner is to leave the scanner unplugged, reboot, then plug the scanner in once Windows has been loaded. If the scanner is plugged in during a reboot or shutdown, it will be seen as an "Unkown Device" by the computer. There was a USB camera plugged in before all this and it was working fine and now I'm having the same "Unkown Device" problem with the camera.

The computer is a Compaq Presario 7478. The computer has not given my uncle any problems until I attempted to install the scanner.

Any help would be appreciated....
