Hi Jay,
|
|
<BR>
|
|
<P>It will be useful every different combination of scanning, but trying
|
|
<BR>
|
|
to understand button polls is a good way to start coding and testing.
|
|
<BR>
|
|
That's the first thing the hp4200 test program could do, and also for
|
|
<BR>
|
|
the IBM Ideascan (<A HREF="http://ideascan.sourceforge.net">http://ideascan.sourceforge.net</A>)
|
|
<BR>
|
|
<P>To understand (only) the scanning protocol, it will be better to
|
|
<BR>
|
|
exclude the button polls from the log file.
|
|
<BR>
|
|
<P>It will be nice to publish all those log files in the WWW, so people
|
|
<BR>
|
|
interested in those files, or just curious people, can view/download
|
|
<BR>
|
|
them. Maybe opening a sourceforge project could be the easier way.
|
|
<BR>
|
|
<P>Please, don't forget to annotate the scanning parameters used to
|
|
<BR>
|
|
generate those log files! (and save the scanned image)
|
|
<BR>
|
|
<P>Cheers,
|
|
<BR>
|

<P><EM>>The extra traffic in the control URB's may be due to the process which

<EM>>3300 I noticed that the log had data being collected even when the scan
