Since my LiDE 60 works without any additional driver, it must be
supported directly by sane itself. Looking through /etc/sane.d/*.conf, I
found an entry for it in /etc/sane.d/genesys.conf (which makes sense
given the result above from running 'scanimage -L').

Since your device is fairly new, I wonder if it will be recognised by
just adding an entry for it, along with the others,  in
/etc/sane.d/genesys.conf - something like:

# Canon LiDE 400
usb 0x04a9 0x1912

If it doesn't work in genesys.conf (I just suggest that first because
all the other LiDE's are in there), then you could try putting it in
/etc/sane.d/pixma.conf, although that seems set up for networked devices
rather than USB.
