|

<BR>
|
||
<P><EM>> 2) Using the sourceforge driver, which had 1212U in the .h file:
|
||
</EM><BR>
|
||
<EM>> I Had to add 1212U_2 there, else it didn't recognize it.
|
||
</EM><BR>
|
||
<EM>> Then, the same problem as 310/300 above.
|
||
</EM><BR>
|
||
<P>I suggest you keep on trying with this version as it is the latest.
|
||
<BR>
|
||
<P>Have you updated the firmware of your scanner like it is explained
|
||
<BR>
|
||
here:
|
||
<BR>
|
||
<A HREF="http://snapscan.sourceforge.net/#usb">http://snapscan.sourceforge.net/#usb</A>
|
||
<BR>
|
||
<P><EM>> This should be some (simple?) juggling with sizes. Probably due to
|
||
</EM><BR>
|
||
<EM>> different organizing of the data coming from the scanner. Maybe due
|
||
</EM><BR>
|
||
<EM>> to the 36 bit scheme? I'll try and find where this is done, though I'd
|
||
</EM><BR>
|
||
<EM>> appreciate any hint as to where to look.
|
||
</EM><BR>
|
||
<P>My suggestion: the model type is used at many places in the code to
|
||
<BR>
|
||
change the behaviour. It is possible that no defined scanner has
|
||
<BR>
|
||
exactly the same behaviour as yours. So what I would do is take the
|
||
<BR>
|
||
model that seems to work the best and then look for places with this
|
||
<BR>
|
||
kind of code :
|
||
<BR>
|
||
<P>if(ps->pss->pdev->model == MODEL)
|
||
<BR>
|
||
behaviour 1
|
||
<BR>
|
||
else
|
||
<BR>
|
||
behaviour 2
|
||
<BR>
|
||
<P>Then step by step, try to inverse the behaviour (if it does behavior 1
|
||
<BR>
|
||
try to modify it so it does behavior 2). Then try to see if it is
|
||
<BR>
|
||
better or worse. You may finally find the correct behaviour for your
|
||
<BR>
|
||
model, then we will be able to add a new model corresponding to your
|
||
<BR>
|
||
scanner.
|
||
<BR>
|
||
<P><EM>> Maybe I could send you a small image - this could indicate where
|
||
</EM><BR>
|
||
<EM>> the problem is.
|
||
</EM><BR>
|
||
<P>Send it to me if you want, or put it on a web page to avoid loading
|
||
<BR>
|
||
the mailing list. I will see if it looks like one of the problem we
|
||
<BR>
|
||
allready had.
|
||
<BR>
