<i>&gt; &gt; The vendor string consists of 8 spaces, and the model string is simply</i><br>
<i>&gt; &gt; "Flatbed Scanner ".</i><br>
<i>&gt; </i><br>
<i>&gt; &gt;From looking at this, it does show that your Product revision is 1.90</i><br>
<i>&gt; (bytes 32-35). That is the same revision level as my AT3, so it looks</i><br>
<i>&gt; like they might be the same exact thing. I also looked at BlackWidow's</i><br>
<i>&gt; webpage and the scanner looks like my AT3 with the image reversed left</i><br>
<i>&gt; to right. On mine the label is on the right and in the pic it's on the</i><br>
<i>&gt; left front. Which side is yours on?</i><br>
<i>&gt; </i><br>
<i>&gt; &gt; Rather tacky rebadging if you ask me.</i><br>
<i>&gt; </i><br>
<i>&gt; Ditto.</i><br>
<p>
Me too :).<br>
<p>
If you are planning to integrate support for this model into the<br>
Artec backend, please make sure that the backend does not only check the<br>
vendor id in the inquiry information to decide, whether it should handle<br>
the device.<br>
<p>
The problem here is that the vendor string is not unique, because<br>
Microtek uses the same eight spaces as vendor id for their scanners.<br>
<p>
check for "result + 36 == 0x00", because microtek2 expects a<br>
model code !=0 at this position.<br>
<p>
I also looked into the documentation for the devices that are supported<br>
by the microtek(1) backend, and according to the specs, they return<br>
some vendor specific ASCII string, starting at that position, so that this<br>
check should be save.<br>
<p>
Nevertheless, I don't know whether it is actually the case, that an<br>
ASCII string is always there (Matto ?).<br>
