The scanner isn't found anymore.

See above, "scanimage -L" no longer worked. sane-find-scanner does not
seem to affected by SANE_CONFIG_DIR at all. Why did you ask?

Of course. I know this now. But again, see above, when I did the
configuration according to the (long) README the situation so far only
I am currently trying to get network scanning with saned working which
seems to be a prerequisite step before for scanbd config (except that of
course, scanbd works fine from the command-line, go figure).
Couple of questions. Should I see scanbm or "scanbd -m" in the list of
running processes? What I get here is "/usr/sbin/scanbd -c
/etc/scanbd/scanbd.conf". Am I correct to assume that scanning over the
network (even if the network is only 127.0.0.1) is a prerequisite before
I have now temporarily set /etc/sane.d/dll.conf to contain only the net
backend. net.conf in the same directory defines saned hosts at
localhost and 127.0.0.1. "nmap localhost" shows the sane-port at 6566
to be open. But "SANE_CONFIG_DIR=/etc/sane.d scanimage -L" either
crashes outright or does not find any scanner. The strange thing having
both the net and genesys backend in there results in either a crash or
$ SANE_CONFIG_DIR=/etc/sane.d scanimage -L
device `genesys:libusb:002:011' is a Canon LiDE 35/40/50 flatbed scanner
device `net:127.0.0.1:genesys:libusb:002:011' is a Canon LiDE 35/40/50
device `net:localhost:genesys:libusb:002:011' is a Canon LiDE 35/40/50
I am starting to wonder if the version 1.0.23 in trusty is simply
terribly buggy to the point of being unusable.
