Hello,
I found some solution for my problem :
First, I noticed than the file scanbd_dbus.conf wasn't in the system.d
folder, so I added it.
The error changed : no more dbus connection error but endless
Iteration on dbus call in the log...
It seems that if I start scanbd right after inetd, this error shows.
Bur if I start inetd, then do a scanimage -L or another use of the
scanner via sane, then start scanbd, it works like a charm !
So I modify the udev rule so that when the scanner is turned on, it
launches inetd, then imagescan -L, then scanbd :
# Epson Perfection V500 Photo
ENV{ID_VENDOR_ID}==04b8, ENV{ID_MODEL_ID}==0130, ACTION==add,
RUN+=/usr/sbin/service inetutils-inetd start,
RUN+=/usr/bin/scanimage -L, RUN+=/usr/sbin/service scanbd start
ENV{ID_VENDOR_ID}==04b8, ENV{ID_MODEL_ID}==0130, ACTION==remove,
RUN+=/usr/sbin/service scanbd stop, RUN+=/usr/sbin/service
inetutils-inetd stop
I don't know if it is a configuration problem or a bug...
Best regard

Hello,
Something strange happened :
2 months ago,I managed to get scanbd to work perfectly with my
epson V500 scanner, built my own script, ..., was very proud of
myself...
... until today, where after 2 months of not using it, I tried to
use a button, and it did not work !! I must have changed something,
during those 2 months, but I really don't know what...
So, the scanner is plugged in a Debian 6, the debug log shows these
errors :
scanbd: start dbus thread scanbd: Not Primary Owner (-1) scanbd:
Name Error (Connection :1.8 is not allowed to own the service
de.kmux.scanbd.server due to security policies in the
configuration
and later :
scanbd: polling device Perfection V500 scanbd:
epson-vphoto-backend: communication error: read length:0
(expected:1)
(the full log is pasted afterwards)
I tried to modify the user/group in scanbd.conf (trying lp, saned,
scanner, root..) with no change.
The UDEV rule for the scanner seems to make it belong to the
scanner group : ATTRS{idVendor}==04b8,
ATTRS{idProduct}==0130, MODE=0664, GROUP=scanner,
ENV{libsane_matched}=yes
Don't hesitate to ask me for more informations if needed...
Thanks for your help !
