Hi,<br>
|
||
<p>
|
||
some weeks ago someone asked, whether his "Black Widow" scanner is<br>
|
||
supported by sane, and I suggested to try it with one of the microtek<br>
|
||
backends, because it was mentioned, that this device had an "empty"<br>
|
||
vendor string in its inquiry information.<br>
|
||
<p>
|
||
In the meanwhile I have received the complete inquiry information, which is<br>
|
||
as follows:<br>
|
||
<p>
|
||
[inquiryresult]<br>
|
||
0: 060002015b000000<br>
|
||
8: 2020202020202020<br>
|
||
16: 466c617462656420<br>
|
||
24: 5363616e6e657220<br>
|
||
32: 312e393000000000<br>
|
||
40: 0000000000000000<br>
|
||
48: 0000000000000000<br>
|
||
56: 0000000000000000<br>
|
||
64: 0000000000000000<br>
|
||
72: 0000000000000000<br>
|
||
80: 0000000000000000<br>
|
||
96: 0000000000000000<br>
|
||
<p>
|
||
The vendor string consists of 8 spaces, and the model string is simply<br>
|
||
"Flatbed Scanner ".<br>
|
||
<p>
|
||
The inquiry information looks similar to what the microtek2 backend<br>
|
||
expects.<br>
|
||
<p>
|
||
- Microtek uses 8 spaces as a vendor id.<br>
|
||
<p>
|
||
- The format of the revision level is the same as for Microtek devices<br>
|
||
(1 digit major revision, then a dot, then 2 digits minor revision level).<br>
|
||
Of course, other manufacturers may use this format as well.<br>
|
||
<p>
|
||
But there are also some things, that are unusual for Microtek scanners.<br>
|
||
<p>
|
||
- The response type code is 0x01 instead of 0x02, which, according to<br>
|
||
my understanding of the SCSI-2 spec, means, that it is some kind<br>
|
||
of pre-SCSI-2 standard (CCS). I don't know, if a backend should take<br>
|
||
care of this.<br>
|
||
<p>
|
||
- Normally there is a model code != 0x00 at inquiryresult[36].<br>
|
||
<p>
|
||
If the backend is modified to accept a model code of 0x00 the system locks<br>
|
||
up, when the next SCSI command is executed, which is a vendor specific<br>
|
||
read command:<br>
|
||
<p>
|
||
28008200000000001f0000<br>
|
||
<p>
|
||
Since the device does not return a 'check condition' I assume that it<br>
|
||
understands a read with a data type code of 0x82.<br>
|
||
<p>
|
||
Now I am unsure, which company is the manufacturer of this device.<br>
|
||
Especially the vendor id lets me believe, that it is a Microtek, because<br>
|
||
manufacturers should register this vendor string with a committee to<br>
|
||
avoid conflicts.<br>

||
