what is the state for each scanner of the snapscan backend. There are

pb with sane-1.0.3 in 300dpi
|
||
<BR>
|
||
<P><P>I think that my 2 lines modification (adapted to those models) could
|
||
<BR>
|
||
make the 3?0 models work with sane-1.0.1 (the 310s problem at least
|
||
<BR>
|
||
looked very similar to the one I had).
|
||
<BR>
|
||
<P>So by using my 2-lines-patch and usb-patch, I think we would have two
|
||
<BR>
|
||
classes of scanners:
|
||
<BR>
|
||
= 3?0 and 12?? working with sane-1.0.1 up to src-0.8 but block with
|
||
<BR>
|
||
sane-1.0.3 in 300dpi+
|
||
<BR>
|
||
= some 6?0 working with sane-1.0.1 with color problem and sane-1.0.3
|
||
<BR>
|
||
without any problem
|
||
<BR>
|
||
<P>so what can we do?
|
||
<BR>
|
||
= correct the problem in sane-1.0.3 which blocks things (best solution
|
||
<BR>
|
||
but may take some time)
|
||
<BR>
|
||
= correct the color offset problem in sane-1.0.1-0.8 for 6?0 and go
|
||
<BR>
|
||
back to this version (don't know if that is feasible)
|
||
<BR>
|
||
= merge snapscan-0.8 and snapscan-1.0+ but with a big test selecting
|
||
<BR>
|
||
between two behaviours for the source (one old 0.8 way and one new
|
||
<BR>
|
||
1.0+ way) depending on the model.
|
||
<BR>
|
||
<P>I think the last solution could be a good way to escape the problem
|
||
<BR>
|
||
while waiting for a correction to this bug. At least, everybody could
|
||
<BR>
|
||
use the last version of the sane package; the backend in itself would
|
||
<BR>
|
||
just be a bit messy. I may try to make it if there is no other
|
||
<BR>
|
||
solution to have everything work.
