this should not be required, but you need to set the SANE_CONFIG_DIR
env. variable before starting scanbd (see below)

A few notes:
scanbd_dbus shall be copied into /etc/dbus-1/system.d, that is what you
referred to I guess?
What do you use to start scanbd? Systemd? Scanbd apparently does not see
the scanner. What is set for SANE_CONFIG_DIR? Do you have a dll.conf in
that dir with the appropriate backend for your scanner listed? Does it
have the config file for the backend (if needed) in that dir? 

kind regards, Louis
