That's ok. For a desktop machine using scanbd and local scanning apps 
(like scanimage), scanbd / scanbm must be running. Please read 0.1)

The below log shows, that scanbd recognizes the scanner and his options. 
So now you have to figure out which buttons correlate to which option 
value changes: just press a button and watch the log. Then you can tweak 
the scripts for the button actions.
