Did as you said. Unplugged the scanner. Uninstalled the USB controllers in sys prop. Rebooted. USB drivers reinstalled. Waited til desktop and plugged the scanner into the front. Nothing showing in the taskbar. Clicked on the scanner software. Clicked on "scanner". The scanner box appeared for the first time!!! Looked like it was going to work. But when I tried a scan it said the scanner was not ready. So I tried to scan again. Then it said the cable was not plugged in. So close!!! Something else I noticed. There is a "direct scan" in the sys try that you can use to save time. It works with the scanner plugged into the back but not the front.
