Also make sure you have the latest scanner drivers and software, but first try unplugging the scanner and plugging it in to a different powered usb port that is on a separate usb channel / bus, that you know is working properly. Sometimes it seems like the computer looses track of some usb devices for some reason( I had it happen a few times on my G4 after waking from sleep) , and stuff needs them to be swapped, or the computer restarted for the usb devices to be re-recognized. If that does not work then try the drivers, and hopefully it is not the case where the drivers are broken because of an os update and no new drivers are available yet... Is anyone able to run their Canoscan software on os 10.3.6, I am running CanoScan Toolbox X 4.1.1.0 on os 10.3.5 with no problems.
