[sane-devel] Problem with Button of HP ScanJet 6200C Scanner and scanbd

Fri Nov 16 06:03:28 UTC 2012

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
