Very much thanks to:
Oliver Neukum who sponsored a HP 5300 USB scanner !!! ;-)
Avision INC for sponsoring a AV 8000S with ADF !!! ;-)
Avision INC for the documentation we got! ;-)

random garbage.
- one-calib-only
- one-calib-only:
When this option is enabled, the backend will only
perform a calibration when the backend is initialized
and not before each scan. This might extend the life
of the CCD, but does not work reliable with the newer
USB scanners (they hang sometimes or return garbage
image data). So this option should be used with care.
- old-calibration:
This enables the use of the old calibration code for
testing purposes.
- disable-c5-guard:
This disables the alpha-quality code normally needed
for newer USB scanners (e.g. HP 5370) to compute some
values for the hardware scaling.
Note: Any option above modifies the default code-flow
for your scanner. The options should only be used
when you encounter problems with the default be-
haviour of the backend. Please report the need of
options to the backend-author so the backend can
be fixed as soon as possible.
