In the meantime I have played around a little bit:
I put vendor and product id's into
/usr/src/sys/dev/usb/uscanner.c and usbdevs and rebuilt
my kernel.
So now I get
   # dmesg | grep uscanner
   uscanner0: <Canon CanoScan, class 255/255, rev 2.00/3.07,
   addr 2> on uhub1
which changes:
   # sane-find-scanner -q
   found USB scanner (vendor=0x04a9, product=0x1900) at
   /dev/uscanner0
Also I tried an appropriate entry in
/usr/local/etc/sane/genesys.conf	
but the result of
   # scanimage -L
remains the same (not identified) and
   # scanimage -d genesys:/dev/uscanner0 > image.pnm
   scanimage: open of device genesys:/dev/uscanner0 failed:
   Invalid argument

Greetings,

Uli.
