Hi...
|
|
<BR>
|
|
<P>I just recompiled sane/xsane for the 2.4.5 kernel I installed, hoping the
|
|
<BR>
|
|
problem would disappear, but no luck.
|
|
<BR>
|
|
<P>When I scan (snapscan 1212U) an image with lots of white (probably
|
|
<BR>
|
|
saturated), the transmission to the PC hangs. Lowering contrast, or
|
|
<BR>
|
|
even turning the original 90 degrees, solves the problem. I suspect the
|
|
<BR>
|
|
image data is compressed when sending though USB. Could there be an
|
|
<BR>
|
|
bug in the protocol? Either in the Snapscan firmware, or at the receiving
|
|
<BR>
|
|
end?
|
|
<BR>
|
|
<P>John
