Hi Ian,<br>
<p>
<i>&gt;&gt;&gt;&gt;&gt; On Fri, 10 Jul 1998 11:04:49 +0100 (BST), Ian Grant &lt;<a href="mailto:I.A.N.Grant@damtp.cam.ac.uk">I.A.N.Grant@damtp.cam.ac.uk</a>&gt; said:</i><br>
<p>
Ian&gt; I'm wondering now how I tell SANE where to find the scanner. My<br>
Ian&gt; system has a /dev/cam device, and I see from sanei_scsi.c that<br>
Ian&gt; for SCSI/CAM sanei_scsi_open expects a device string of the<br>
Ian&gt; form "bNtNlN" where the N's are bus, target and lun, and opens<br>
Ian&gt; /dev/cam. The trouble is that I can't see where I have to<br>
Ian&gt; specify the bus/target/lun string. For example the sane-hp man<br>
Ian&gt; page says:<br>
<p>
Ian&gt; "This backend expects device names of the form:<br>
<p>
Ian&gt; special<br>
<p>
Ian&gt; Where special is the UNIX path-name for the special<br>
Ian&gt; device that corresponds to the scanner.<br>
<p>
Ian&gt; Is this just a bug in the man page, and should I be putting<br>
Ian&gt; b0t2l0 or whatever in the hp.conf file?<br>
<p>
Yes, you're supposed to put b0t2l0 in hp.conf.<br>
<p>
Ian&gt; Also, can anyone tell me how buggy the user-level scsi<br>
Ian&gt; interface is? I.e does it trash disks? What sort of bugs<br>
Ian&gt; should I expect?<br>
<p>
As I mentioned earlier, expect it to be buggy. I wrote that code<br>
based on some DUX docs and I'm pretty sure some things are not quite<br>
right. It has the potential to trash the disks.<br>
