Hi.<br>
<p>
I've attached a patch for microtek.c which lets me use the ADF on my<br>
ScanMaker IIG. A couple of notes:<br>
<p>
1. The line where the paper length is calculated generated strange<br>
numbers for me - my patch includes a change which fixes it, but I have<br>
only tested it with my scanner :-(<br>
<p>
2. My scanner gets this message:<br>
<p>
scsi0 : weirdness<br>
STATUS_REG: 00<br>
BASR: 08<br>
ICR: 00<br>
MODE: 00<br>
<p>
many times while the scan head is returning after a scan. Does anyone<br>
know what causes this?<br>
<p>
