About two years ago I was advised that the environment variable SANE_FUJITSU_DEBUG=15 would generate a bunch of output to stderr.
I tried it yesterday on Bionic and failed to see output. I tried SANE_FUJITSU_DEBUG=15 scanimage ... and export SANE_FUJITSU_DEBUG=15 scanimage ... Is there something else I need to do? Perhaps a debug command line option? Unfortunately, I only have brief slots of time available to work with the scanner, so I am trying to be as prepared as I can for my next slot. Thanks.
