<i>&gt; Phantom [something]...</i><br>
<p>
It is normal that the vendor string for Microtek scanners consists<br>
of eight spaces. However, normally the model is specified more<br>
exact, for instance 'Scanner 636A4'. If it is a model which should be<br>
supported by the microtek2 backend, it won't work at all until this<br>
model is known to the backend. Thus it would be interesting what<br>
'[something]' is.<br>
<p>
The backend does some checks on the inquiry information, and refuses<br>
to work if it finds information, that it doesn't expect. For instance<br>
the models it supports are all SCSI-2 devices, and therefore<br>
it checks for an ANSI SCSI revision of 02.<br>
<p>
Does anybody have an idea, why /proc/scsi/scsi says revision 04 ?<br>
<p>
Then the backend checks for a model code. You should enable<br>
debugging (set SANE_DEBUG_MICROTEK2=30) to get the model code, once<br>
you get past the check for the SCSI version.<br>
