<i>&gt; Quick question on xscanimage.</i><br>
<i>&gt; When I fire up xscanimage it says that i can choose pnm:0 or pnm:1</i><br>
<i>&gt; What are these and where do i link to my scanner which is on /dev/sda4?</i><br>
<p>
These are "pseudo" sources which can be used to read pnm-files. Choose<br>
one, enter a existant filename (containing a pnm of course :-), and you <br>
will see.<br>
<p>
If you cannot access your scanner in this list, it is not configured <br>
correctly or has lacking permissions.<br>
<p>
Check /usr/local/etc/sane.d/dll.conf, if it contains the necessary drivers<br>
e.g. net pnm and mustek for me and the mustek.conf (or equivalent, depending<br>
on your scanner), if it has the right device entry.<br>
<p>
Moreover I doubt, that your scanner is on /dev/sda4. sda4 is a harddisk <br>
partition, and if a scanner really really says it is a HD partition (which<br>
none of the supported scanners does AFAIK), the HW developer should be forced<br>
to eat it.<br>
<p>
Scanners are accessed via /dev/sg? devices which requires SCSI-generic support <br>
in the kernel and devices are counted for getting the ?.<br>
<p>
I.e. if the scanner is the first entry in /proc/scsi/scsi this is sga, <br>
2nd is sgb, ...<br>
