I do sane-find-scanner and get:

found USB scanner (vendor=0x04a9 [Canon], product=0x2220 [CanoScan]) at libusb:002:002
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

scanimage -L tells me:

No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate).

The list of supported scanners says it is the same manpage as plustek.

My canon.conf file contains:

#canon.conf
#usb
[usb] 0x04a9 0x2220
device /dev/usbscanner

Anything else I should try ?

The scanner has been well supported earlier. At the moment he is no longer in the list of supported devices.

Here are some options:

I have a Dell optiplex with ubuntu 14.04 LTS. I had the same problem with the sanner Canon Lide 25. I search a solution in different direction.

Finally, I have desactivated usb 3.0 in the bios (only using the 2.0 usb), and now the scanner works fine (with xsane or simple-scan) without any need to parametrize config files (just plug the scanner it works)!

Hope that it will help someone
