My Canon scanner (canonlide 50) has stopped working suddenly. I get the message "Cannot communicate with scanner, cable maybe diconnected, check status etc" and then the message "unable to open Twain source, please check connection" I have changed the USB 2 cables, changed the usb ports, deleted the driver and reinstalled, unplugged the scanner and then connected it up again and still no joy. In device manger the scanner report says it has no problems and is working fine, but the status says unavailable. I set the scanner up on my old Win98 machine and it works fine albeit a bit slower on a USB1 connection! So the scanner is still working it seems but not in Win xp home anymore. Does anybody have any suggestions? I e-mailed Canon- UK and as yet have had no reply!!
