Hi Dio,

the code needed for button support is now available in the genesys
backend from sane-backends cvs. If you did not already find it, there is
sanebuttonsd in experimental cvs(in button-daemon/). It works great if
you reduce the sleep at the end of the mainloop to 100ms
(f.e. usleep(100000)).

This is for Canon LiDE 35/40/50 only, so if anyone with a Canon LiDE 60
wants his scanners buttons to work, he needs to add the flags for the
buttons to the corresponding model struct and try if that works.

Regards,
