As it turns out, that was the sole problem -
all that is required is byte swapping in four places in genesys_low.c
(i.e. lines 265,269,387, and 391: replace 'value' with something like
'bsuint16(value)' ); everything else appears to be working as perfectly
as can be expected for a scanner in this price class.
Question:
Would there be a point in me creating a proper patch, or do you think
there is insufficient demand for this?
