183 of the USB 1.1 spec. In the originating URB this information

has already been decoded for you by usbsnoopy.

<BR>
|
|
<P><EM>> - but unfortunately I'm not too clued up on USB programming; the
|
|
</EM><BR>
|
|
<EM>> documentation at www.usb.org isn't exactly in plain English.
|
|
</EM><BR>
|

<EM>>
|

</EM><BR>
|
|
<EM>> Please could someone enlighten me as to how to go about deciphering this
|
|
</EM><BR>
|
|
<EM>> output (produced when I plugged the scanner in under Win98) and reproduce
|
|
</EM><BR>
|
|
<EM>> the effect under Linux (possibly as some variant of Vladimir's ct.c code.
|
|
</EM><BR>
|
|
<P>We have some perl scripts that can extract relevant info from the
|
|
<BR>
|
|
logs. The scripts are specific to the Microtek Scanmaker 3600
|
|
<BR>
|
|
would proabably provide you with a good starting point.
|
|
<BR>
|
|
<P>Have a look at <A HREF="http://sm3600.sourceforge.net">http://sm3600.sourceforge.net</A> for some backgound
|
|
<BR>
|
|
info and get the microtek3600.tar.gz tarball from
|
|
<BR>
|
|
<A HREF="http://privat.schlund.de/eichholz">http://privat.schlund.de/eichholz</A> (it will also be in CVS on
|
|
<BR>
|
|
sourceforge soon, this weekend maybe).
|
|
<BR>
|
|
<P>There is also a modifed version of usbsnoopy that does not log the
|
|
<BR>
|
|
bulk transfer buffer. We found that the debugview program couldn't
|
|
<BR>
|
|
keep up with the messages and we were losing important parts of
|
|
<BR>
|
|
the logs. I'm not sure if it is available for downloaded yet but
|
|
<BR>
|
|
mail me if you want it.
|
|
<BR>
|
|
<P>As for reproducing the ouptut, if you are using Linux, there is a
|
|
<BR>
|
|
tool called usb-robot available from sourceforge. It can replay
|
|
<BR>
|
|
some snoopy logs using libusb, it didn't work for the scanmaker
|
|
<BR>
|
|
3600 but provided a good starting point and is an example of how
|
|
<BR>
|
|
to use libusb.
|
|
<BR>
