Well, it seems I can reproduce it reliably by repeatedly pressing a
button on my CanoScan 9000F before the child (action) process exits. I
do not have access to another scanner to test if this is a common
behaviour or not.
  
  Is there any SIGNAL I could send to scanbd process to refresh itself
  without the need to restart scanbd.service?
 
 Try to send SIGUSR1 to stop all polling and then SIGUSR2 to restart all
 polling.

The signals were caught by the process and it responded as described,
however, it did not resolve the bug.

I will report this behaviour in the Discussion forum of
Sourceforge.net / scanbd so that it does not get lost.

regards,
Milan

Re: [sane-devel] Pixma: ADF paper empty patch for Canon Pixma MX???

2014-05-17 Thread Matthias Peter Walther 
Hallo Rolf,

I'm sorry, I couldn't reply earlier. I had some issues with my pc, hdd
crash.

I pulled the patch from the git and I can't get higher resolutions than
75 anymore while using the ADF. It resets the resolution back to 75 all
the time.

But the out-of-paper issues works great and the scaner recovers
perfectly from the error state now.

Could you look into that resolution issue please?
