Hi all, <br>
<p>
I got my Mustek MFS 12000 SP the day before yesterday. Yesterday I played<br>
around in Win 3.1. The scanner worked, so I tried to get the thing working<br>
in Linux, with the original SCSI card. No luck. <br>
<p>
Yesterday I tried again. I had applied the mustek-scsi-patch-0.5.gz to<br>
Linux 3.0.30 (I know I should get pl 32, next thing on my list) and<br>
had gotten one reject, for the Makefile in the drivers/scsi directory. <br>
<p>
This Makefile has to be edited by hand, as commented also in the patch (I<br>
figured it out myself before I read it well, always RTFM 2x). My card was<br>
the DTC3181E, a thing that I had written down in the Mustek manual. This<br>
is another lesson from practice, write down the funny codes on the chips<br>
and the jumper settings (if any), before you build in the card. The patch,<br>
and the comment in the patch are not quite up to date for the newer Linux<br>
kernels, but it is easy to find the corresponding bit to change, just look<br>
for the GENERIC_NCR5380_OVERRIDE flag. <br>
<p>
Once I had done that, the card was recognised at boot time. The scanner<br>
device ends up at /dev/sga (Redhat 4.0), and scanimage can recognize it. <br>
<p>
To my surprise, the scanner works faster now than under Win 3.1! The<br>
machine does not lock up, as claimed for the original 0.2 patch. (and I<br>
verified that for Win 3.1 it does lock up -- totally. This was no surprise<br>
however.) Checking the load with top while doing a scan returns 90% idle<br>
time for the CPU.<br>
<p>
Now the only problem I have is that the colours get mixed up on larger<br>
scans. From mailing list I guess I am not alone, and that it affects other<br>
SCSI cards too. I will next try the MUSTEK_FLAG_LD_NONE, and you'll hear<br>
of the results.<br>
<p>
Bye<br>
	Ren<65><br>
