Added support for the Avision AV210D2+ scanner. This is the first scanner
to require the use of the gray filter bits, so code was added to enable them.
Regenerated description file to reflect this change.
Moved device init code from sane_init() to the newly created
sane_reload_devices() function, which is now called from sane_get_devices().
This means that device initialization now happens when sane_get_devices() is
called, not when sane_init() is called.
Replaced the clever, yet totally confusing, code using the "adf_mode"
variable. This variable was used with a complex interaction of bit shifts
and subtraction indirectly influnced by the value of s->source_mode. The
replacement code direct references s->source_mode instead, simplifying
things greatly. This change is functionally identical.
As a side note, the adf_mode code allowed "ADF Rear" scanners, in addition to
"ADF Duplex" scanners, to enter the section of code normally used for (HP)
duplex scanners. It's not clear if this was the intended effect, or if, as
the comments suggest, this was an unnoticed side effect caused by the
confusing code. The point is moot, however, because prior in the code, the
ADF Duplex flag is set anytime the ADF Rear flag is set. As long as all
ADF Rear scanners are duplex scanners this shouldn't be a problem.
Changed the AVISION_FILTER_* defines to their final values rather than
bit-shifting them prior to use. This make reading the code much easier
since no mental calculation is necessary to determine what the final
bit-pattern/value will be.
Wrap scanner entries with duplicate USB ids with ifdefs so they will not be
compiled. This shortens the search for new scanners because we don't try
the same USB id more than once.
create a place holder for low level commands
move low level functions to genesys_low.c
