[sane-devel] Epson GT6000 parport scanner on RH Linux

[Karl Heinz Kremer]

Eric,

please try the attached patch  and let me know if this helps to 
not detect the ADF. It's agains the 1.0.12 version that was just
released. It should not be too difficult to manally apply the
changes to an older version.
