With the latest CVS-Release I successfully build sane-backends. The libsane-genesys is included. When I run sane-find-scanner I get this
$ sane-find-scanner ... found USB scanner (vendor=0x04a9, product=0x2215, chip=GL660+GL646?) at libusb:003:007 # Your USB scanner was (probably) detected. It may or may not be supported by # SANE. Try scanimage -L and read the backend's manpage. ... After reading the man of sane-genesys I found out that I could add my own scanners by adding them to /usr/local/etc/sane.d/genesys.conf. I did it with the data above. But scanimage -L still doesn't detect my CanoScan 3000! What am I doing wrong? Regards Christian
