FYI when i google i found scanbuttond project that supports few
scanners to have their buttons working fine.
Current supported scanner list by this project can be found at
http://scanbuttond.sourceforge.net/index.php?page=/Supported_Scanners.php
I don't know currently what type of functionality is added in
CVS tree and for which scanners?
