Hi !<br>
<p>
<i>&gt; Actually now that I double checked it was linked from as the ID of the scanner</i><br>
<i>&gt; is 5 the device is /dev/sgf. But using that device gives me still the same </i><br>
<i>&gt; error.</i><br>
Stop ... Linux doesn't map ID-to-minor.<br>
<p>
<i>&gt; Now I noticed running scanimage on virtual terminal that there was a message say</i><br>
<i>&gt; ing:</i><br>
<i>&gt; Detected scsi general sga at scsi0, channel 0, id 5, lun 0</i><br>
Then sga is probably correct. Linux checks for the device-type, ans maps <br>
e.g. harddisks on sda,sdb,..., cdrom on sr0,... etc. It look you scanner is <br>
the only device on the bus, or none has ID&lt;5.<br>
<p>
<i>&gt; This didn't show up when I run it on xterm, and still doesn't. I wonder why it</i><br>
<i>&gt; says sga and id5 shouldn't sga be id 0 and id5 be sgf. This seems strange to me.</i><br>
No. Linux is maybe a bit strange in this respect - maybe they wanted to save <br>
some minors ...<br>
<p>
Moreover be careful about setting proper permissions. Use strace to check the<br>
exact cause of the abort, if there are still problems ...<br>
<p>
