Well, the old scanbuttond has the disadvantage, that it blocks other 
appliations from scanning at the same time it polls the buttons.

This is the reason for scanbd being:

http://sourceforge.net/projects/scanbd/

[
scanbd is a scanner button daemon. It polls the scanner buttons looking
for buttons pressed or function knob changes or other scanner events  as 
paper inserts / removals and at the same time allows
also scan-applications to access the scanners. If buttons are pressed,
etc., various actions can be submitted (scan, copy, email, ...) via 
action scripts. The function knob values are passed to the 
action-scripts as well. Scan actions are also signaled via dbus. This 
can be useful for foreign applications. Scans can also be triggered via 
dbus from foreign applications.
On platforms which support signaling of dynamic device insertion / 
removal (libudev, dbus, hal) scanbd supports this as well.
scanbd can use all sane-backends or some special backends from the (old) 
scanbuttond project.
Supported platforms: Linux, FreeBSD, NetBSD, OpenBSD
]

It normally uses the sane-backends, but can also use the old drivers 
from the scanbuttond (included into scanbd).

Please change the dimension also to 3 or use NUM_SUPPORTED_USB_DEVICES!
