scanbd doesn't work unless I restart it from the command line

NAME "Raspbian GNU/Linux" VERSION_ID "7" VERSION "7 (wheezy)”

Linux raspberrypi 3.18.7+ #755 PREEMPT Thu Feb 12 17:14:31 GMT 2015 armv6l GNU/Linux

I’ve installed SANE and scanbd with a Canoscan LIDA 210. From Instructions Here I’ve put in an /etc/init.d script copied from the example script that came with scanbd. The only modifications are to the paths, and I added ‘$ALL’ to the Required-Start:’.

THE ISSUE IS: The scanner buttons won’t work until I re-start the scanbd process manually from the command line, as root, using ‘service scanbd restart’. Then all is good. The service still appears to be running as saned.

But this is a project that will not have a head…so this will not work in the long run. I have been working under the assumption that the startup may simply be occurring too soon in the boot process, but this may not be the issue.

Please see code below.

=== After reboot, BEFORE service restart ===

root@raspberrypi:/home/pi# ps -ef  | grep -i scan
saned     3119     1  0 09:40 ?        00:00:00 /usr/local/sbin/scanbd -c /usr/local/etc/scanbd/scanbd.conf
root      3242  3239  0 09:41 pts/0    00:00:00 grep -i scan

=== service scanbd restart ===

root@raspberrypi:/etc/init.d# service scanbd restart
