Canon 1220U scanner that I've had running with no problems for the past several months suddenly stopped working. I uninstalled the driver and scanner software so as to get a clean reinstall. Plugging in the usb cable (to either port, both of which work fine with HP 930 inkjet)resulted in an 'unknown device' and I have been unable to replace the resulting generic driver with the one from the Canon CDROM or one downloaded from Canon's site. My machine uses the Intel AB/EB host controller on an HP Pavilion 8570C - diagnostic software found on this site reports that the controller is running fine. I only use the two usb ports that came with the machine. Canon emailed me a nice set of clear troubleshooting procedures but that I went through step by step but that didn't help.
I'm not sure exactly when scanner stopped working, but in the past week or two the following events have occurred (not necessarily in the order stated):
* Pavilion memory upgraded from 96 to 192 MB
* Homelink phoneline network card and software installed (network not working yet, either)
* nimda virus eliminated with the help of Norton's tool
* klezmer viruses eliminated with the help of Norton's tool. (machine seems clean now).
* 2 minute power outage uccurred. Computer continued to run fine on UPS -- scanner gets its power from computer via usb.
As you can see it's been an interesting week. Can someone tell me how to get this scanner running again?
