<EM>&gt; Following Oliver's earlier advise I deleted /dev/scanner and I now skip
</EM><BR>
<EM>&gt; the 'pick a scanner' screen. Interestingly, sg1 is a link to sgb. I can
</EM><BR>
<EM>&gt; only assume that xsane is checking /dev/scanner and /dev/sg[a-h], but
</EM><BR>
<EM>&gt; not /dev/sg[0-9].

<P>Hi Bob,
<BR>
<P>that has nothing to do with xsane, it is done in the backend.
<BR>
<P>A typicall backnd.conf (here umax.conf) looks something like that:
<BR>
<P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;scsi UMAX * Scanner
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/dev/scanner
<BR>
<P>The first line is for linux and this means the backend
<BR>
(there is a lib in the sane package that does it for all sane backends)
<BR>
searches all generic scsi devices (/dev/sg*) for vendor=id=&quot;UMAX&quot;
<BR>
and type=6 (Scanner). The lib is intelligent enough to know that
<BR>
/dev/sg1 and /dev/sgb are the same.
<BR>
<P>the second line &quot;/dev/scanner&quot; is for non-linux-systems. Here the user
<BR>
has to tell sane to which device-file the scanner is connected.
<BR>
<P>Bye
<BR>
Oliver
