Hello everybody, here some additional information to my problem:
I got the following error message from scanimage -L while debug flag is set: root at tux /etc/sane.d # SANE_DEBUG_GENESYS=128 scanimage -L [sanei_debug] Setting debug level of genesys to 128.

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).
