Hello,
the comment and the code are misleading, it is an unclean leftover of a
timeout I have crudely removed since it was more an annoyance than a cure.
The code is looping until head is parked, if your hardware doesn't
park,
a timeout won't help. Could you run scanimage with :
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL646=255
and send me the debug output so I can have an idea of the problem ?
You should really consider using 1.0.22 since the genesys backend is
regularly improved. By using an old release you are at risk of trying to fix
an already fixed bug, or missing support for new scanner models.

Stef
