<p>
Jens Herrmann (jemihe at gmx.de) mentioned on sane-devel: <a
href="http://jens-herrmann.gmxhome.de/MB-D1250U2.JPG">Photo</a> of chipset
<p>
<pre>
From left to right:
* IC1: http://jens-herrmann.gmxhome.de/IC1.JPG
is a IS41C16256-25K (DRAM)
* IC2: http://jens-herrmann.gmxhome.de/IC2.JPG
128 Pin, has no logo or type on it, the 610800009721 is a Part-Nr. .
I was not able to identify this IC.
* IC3: http://jens-herrmann.gmxhome.de/IC3.JPG
is a L66219 (Step-Motor driver)
* IC4: http://jens-herrmann.gmxhome.de/IC4.JPG
48 Pin, has no logo or type on it, the 610800010009 is a Part-Nr. which is listed here
http://www.hkinventory.com/public/OfferInventResult.asp?Order=1&pnums=610800010009&crit1=+&crit2=&category=&product=&keywords=&words=3&country=&postdate=&brand=&crit3=&crit4=0&da+tecode=
and here
http://www.hobid.com/bin/sep.php
when you search for it, but the type can't be found there too.
I was not able to identify this IC either.

<h1>Want to add or correct information?</h1>
<p>
If anything is wrong or missing on this page please <a href="../bugs.html">file a bug report</a>
or use the <a href="http://www.meier-geinitz.de:80/tinc?key=rDoQ7lrj&#38;formname=adddev" target="_top">the
form for adding an unsupported device</a>.
</p>
<p>
If you own an unsupported scanner, please send as much information as
possible. Especially the output of <em>sane-find-scanner -v -v</em>
and/or <em>cat /proc/scsi/scsi</em> (for SCSI scanners) or <em>cat
/proc/bus/usb/devices</em> (for USB scanners) can help. If you dare to
open the scanner, have a look at the text that's printed on the
chips. That may help to identify the chipset. If you know that the
scanner is similar to another one (e.g. supported by the same Windows
driver), please also mention this fact.
</p>
<h1><a href="../manufacturers.html">Information for Manufacturers</a></h1>
<p>
Are you a manufacturer or vendor of scanners and one of your scanners is
not supported by SANE yet? In this case please have a look at our <a
