<i>&gt; &gt;From the scanner attributes that were printed to stderr, I assume that</i><br>

<i>&gt; </i><br>
<i>&gt; But it is very strange, that the application hangs at a "test unit ready".</i><br>
<i>&gt; This is perhaps the most simple SCSI command at all and should at least</i><br>

<i>&gt; independent.</i><br>
<i>&gt; </i><br>
<i>&gt; Does it always hang at this command ?</i><br>
<i>&gt; </i><br>
<p>
Yes.<br>
<p>
<i>&gt; Can you check, what happens, if you remove the scsi_test_uni_ready() </i><br>
<i>&gt; call in microtek2.c (it is called in one place) ?</i><br>
<p>
<p>
Here is the last few lines of output:<br>
<p>
[microtek2] scsi_read_system_status: md=0x80b13e0, fd=-1<br>
[microtek2] dump_area2: readsystemstatus<br>
[readsystemstatus]<br>
28008100000000000900<br>
[microtek2] dump_area2: readsystemstatusresult<br>
[readsystemstatusresult]<br>
010000001100000000<br>
<p>
<p>
Again, it hangs at the last line (I let it sit for over a minute)<br>
<p>
Thanks!<br>
