Try running Sane is 1.0.14 (which seems to be identical for all debian releases form oldoldstable to unstable.

The scanner is listed only for the first try and not the second one. After reading the man page I tried the debug environment variable: niehaus@radioactive:~ $ SANE_DEBUG_COOLSCAN3=128 scanimage -L [sanei_debug] Setting debug level of coolscan3 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). Please read the documentation which came with this software (README, FAQ, manpages). [coolscan3] sane_coolscan3_exit I have no idea what this could mean. Any hints for me? Anything I can do to find out why I fail to use the scanner?
