Hello Wilhelm, it's me again. The output of syslog led me to the config files again and I found that I left "lp" as goup in scanbd.conf.
When I changed "goup = lp" to "group = scanner" I can now run: # scanbd -fd -c /usr/local/etc/scanbd/scanbd.conf and I see 28 (output says 29) options for my scanner in the output ((see output below)). As far as I understand the next step would be to look which (if any) of the options changes when I push the button. Is there a way to let scanbd log every option change as I cannot see anything happen, when I press the button while scanbd is polling for option changes (see output below)? Also running in monitor mode like: # scanbd -m -fd -c /usr/local/etc/scanbd/scanbd.conf or # scanbd -m -c /usr/local/etc/scanbd/scanbd.conf do still give me the same output as in my first mail (saned exited with 0). But I did not investigate any further in this direction (yet) and assume that there are still some rights problems that I can hopefully solve on my own. I know you are busy, but any further help/hints with the options thing would be great as I also do not fully understand what is filtered when in scanbd.conf actions in the global section and in actions of the hp section and how it all fits together (e.g. I connot see any option containg "message" so what does "^message.*" filter do?). I read INSTALL but could not find any further doku on that. Thanks again for the support and regards, Thomas root at server:/# scanbd -fd -c /usr/local/etc/scanbd/scanbd.conf scanbd: debug on: level: 7 scanbd: dropping privs to uid saned scanbd: dropping privs to gid scanner scanbd: group scanner has member: scanbd: saned scanbd: me scanbd: drop privileges to gid: 112 scanbd: Running as effective gid 112 scanbd: drop privileges to uid: 103 scanbd: Running as effective uid 103 scanbd: dbus_init scanbd: dbus match type='signal',interface='org.freedesktop.Hal.Manager' scanbd: sane version 1.0 scanbd: Scanning for local-only devices *scanbd: found device: hp:libusb:001:013 Hewlett-Packard ScanJet 62x0C flatbed scanner* scanbd: start_sane_threads scanbd: Starting poll thread for hp:libusb:001:013 scanbd: Thread started for device hp:libusb:001:013 scanbd: start dbus thread scanbd: udev init scanbd: timeout: 500 ms scanbd: sane_poll scanbd: Iteration on dbus call *scanbd: found 29 options for device hp:libusb:001:013* scanbd: sane_find_matching_options scanbd: found 5 actions in section (null) scanbd: checking action scan with filter: ^scan.* scanbd: option[1] for device hp:libusb:001:013 not of type BOOL|INT|FIXED|STRING|BUTTON.
