Trying to help neighbor install new Canon Pixma MP460 but it will not install & gives an error - specified port unknown. I uninstalled all the Canon software through Control Panel/Add/Remove programs & rebooted.
I diligently followed the instructions carefully to install the software from CD BEFORE plugging in the USB cable, I only plugged in the printer when prompted to by the software & when I did the ÃƒÂ¢Ã‚Â€Ã‚Â˜new hardware detectedÃƒÂ¢Ã‚Â€Ã‚Â™ bubble appears in the system tray several times, each showing the correct device (MP460).
Then after about 10 seconds the ÃƒÂ¢Ã‚Â€Ã‚Â˜install new hardwareÃƒÂ¢Ã‚Â€Ã‚Â™ wizard appears stating ÃƒÂ¢Ã‚Â€Ã‚Â˜Error ÃƒÂ¢Ã‚Â€Ã‚Â“ specified port unknownÃƒÂ¢Ã‚Â€Ã‚Â™.
Then the ÃƒÂ¢Ã‚Â€Ã‚Â˜new hardwareÃƒÂ¢Ã‚Â€Ã‚Â™ bubble changes to ÃƒÂ¢Ã‚Â€Ã‚Â˜an error occurred with the installation ÃƒÂ¢Ã‚Â€Ã‚Â¦ your device may not work correctlyÃƒÂ¢Ã‚Â€Ã‚Â™
IÃƒÂ¢Ã‚Â€Ã‚Â™ve tried the following:
- downloaded the latest drivers from the Canon website & used that ÃƒÂ¢Ã‚Â€Ã‚Â“ same error
- installed the software & then plugged in the printer in the front & back usb ports & itÃƒÂ¢Ã‚Â€Ã‚Â™s the same on each
- Other devices work fine in each of the ports
- checked Device Mgr ÃƒÂ¢Ã‚Â€Ã‚Â“ no errors & the printer shows up as an ÃƒÂ¢Ã‚Â€Ã‚Â˜Imaging DeviceÃƒÂ¢Ã‚Â€Ã‚Â™
Not sure what to try next? Any help appreciated, pls
