Thank you for the suggestions. Here is the result of my endeavours, as
you'll see to no avail:

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).

# Hewlett Packard ScanJet 3670c/3690c

genesys is listed in /etc/sane.d/dll.conf and I've moved the entry to
the end of 
the file to make it load as default (according to man sane-dll).

Alas, still no luck. 
Anything else I could try or should I just give it up?

Best regards,
