[sane-devel] scanbd on Raspbian: scanner only sporadically detected

Hi everybody,

I'm currently trying to set up saned with a Canon Pixma MP610 on a Raspberry Pi 3 running the latest Raspbian Jessie. Scanning works well, however I have some trouble gettings scanbd to work reliably. Scanbd will only detect the scanner on startup every once in a while. Log from the last successful start is at


This was a foreground run, unfortunately only on debug level 4. After I terminated this run, I started scanbd via systemd. This did not detect my scanner. All subsequent tries were unsuccessfull as well. Log from one such try at debug level 7 is at


My config files are

/etc/scanbd/scanbd.conf:	http://paste.debian.net/926677
/etc/scanbd/sane.d/saned.conf:	http://paste.debian.net/926680
/etc/scanbd/sane.d/dll.conf:	http://paste.debian.net/926683
/etc/saned/saned.conf:		http://paste.debian.net/926684
/etc/saned/dll.conf:		http://paste.debian.net/926685

What seems weird to me is that scanimage -L detects the scanner reliably every time, both local and remote, so scanbm doesn't seem to share the problem.

Any hints on how to debug this are highly welcome, thanks in advance! If you need any more info, please ask!
