<h1>Scanners not supported by SANE</h1>
<h2>Manufacturer and model</h2>
<p>
Mustek BearPaw 2448 CU Pro
</p>
<h2>Bus type</h2>
<p>
USB
</p>
<h2>Vendor ID</h2>
<p>
0x055f
</p>
<h2>Product ID</h2>
<p>
0x0408
</p>
<h2>Chipset</h2>
<pre>
Controller: SQ113C (Service & Quality, www.sq.com.tw)
- probably contains embeded 8032 or something like this.
Memory: HY57V161610 - Hynix 1Mx16 synchronous? DRAM
A/D: Holtek HT82V36 - one channel(enough for CIS) A/D with serial
configuration iface
http://www.holtek.com.tw/pdf/computer/82v36.pdf
W27C520 - 64k EEPROM, so no need for firmware upload it seems.
AIC1563CS - DC/DC converter probably for higher voltage generation
L6219 - well known stepper motor controller.
</pre>
<h2>Comments</h2>
<p>
Similar to the Mustek BearPaw 2448TA Pro?
</p>

<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
