I found that the plustek, not canon, backend has to be used, so I set this:

plustek:/dev/ugen0
You should set it to :
plustek:libusb:/dev/usb0:/dev/ugen0
Yes, that is better, but still not ready for prime time :-) see below
ian:25$ env | grep SANE
SANE_DEFAULT_DEVICE=plustek:libusb:/dev/usb0:/dev/ugen0

Could you run scanimage in debug mode and post the output.
ian:26$ scanimage --debug -L
device `plustek:libusb:/dev/usb1:/dev/ugen0' is a Canon
N670U/N676U/LiDE20 USB flatbed scanner
default device is `plustek:libusb:/dev/usb0:/dev/ugen0'
ian:27$ scanimage --debug --mode=color --format=tiff >/tmp/id
scanimage: open of device plustek:libusb:/dev/usb0:/dev/ugen0 failed:

Even running the -L twice in a row (after unplugging and reconnecting
the USB cable)
fails on the 2nd try:
ian:29$ scanimage --debug --verbose -L

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). Please read the documentation
which came with this software (README, FAQ, manpages).

Each time I run it there is a long pause - almost exactly 30 seconds
-before it prints the prompt.
Running commands with sudo does not change any behavior.
Thanks
