I can't find this scanner in our lists. I'm not sure if it's supported
at all.

Ok. Can you show us the output from /proc/bus/usb/devices?

If you don't mind to open your scanner, you could also tell us which
chips are used inside.

canon.conf is for canon SCSI scanners (see man sane-canon).

I don't know if your scanner is similar to those devices. If it is,
you could change backend/canon630u-common.c. Search for this line:

  if ((vendor != 0x04a9) || (product != 0x2204))
  
And change it to use your product id. make clean; make ;make install.

But this will only work if your scanner is compatible with the other
canon USB scanners.

Maybe one of the canon maintainers has more information?

Bye,
