Hi,

<EM>&gt; /proc/bus/usb/devices says vendor id=05d8 (Artec/Ultima?),

<EM>&gt; options (vendor=0x05d8 product=0x4002).
</EM><BR>
<P>If it was Mustek 1200 UB compatible, the vendor would be 0x055f and

product 0x0006. Maybe it works with the 1200ub backend nevertheless.
<BR>
<P><EM>&gt; I have sane 1.0.4 installed.
</EM><BR>
<P>and the Mustek 1200UB backend?
<BR>
<P><EM>&gt; scanimage -L says &quot;no SANE devices found&quot;.
</EM><BR>
<EM>&gt; Running &quot;strace scanimage -L says&quot; reveals that /dev/usbscanner
</EM><BR>
<EM>&gt; cannot be openend. &quot;cat /dev/usbscanner&quot; says &quot;No such device&quot;.
</EM><BR>
<EM>&gt; /dev/usbscanner is linked to /dev/usbscanner0, which is device
</EM><BR>
<EM>&gt; 180/48.
</EM><BR>
<P>Probabaly the kernel scanner driver couldn't detect/attach the
<BR>
scanner.
<BR>
<P><EM>&gt; These are the syslog entries:
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; syslog:Apr 27 01:17:54 kunibert usb.c: registered new driver usbscanner
</EM><BR>
<EM>&gt; syslog:Apr 27 01:17:54 kunibert scanner.c: USB Scanner support registered.
</EM><BR>
<EM>&gt; syslog:Apr 27 01:17:54 kunibert scanner.c: probe_scanner: User specified USB
</EM><BR>
<EM>&gt; scanner -- Vendor:Product - 5d8:4002
</EM><BR>
<EM>&gt; syslog:Apr 27 01:17:54 kunibert scanner.c: probe_scanner: Only two or three
</EM><BR>
<EM>&gt; endpoints supported.
</EM><BR>
<EM>&gt; syslog:Apr 27 01:18:41 kunibert scanner.c: open_scanner(0): Unable to access
</EM><BR>
<EM>&gt; minor data
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Any hints?
</EM><BR>
<P>The scanner module doesn't seem to be able to manage this scanner.
<BR>
However, I don't know which additional endpoints the scanner supports.
<BR>
Probabaly it's the best thing to contact one of the usb mailing lists
<BR>
or the dveleoper of the Linux scanner module.
<BR>
<P><EM>&gt; Is this really a sane problem (no backend found) or some
</EM><BR>
<EM>&gt; misconfiguration within the usb layer?
</EM><BR>
<P>The scanner module seems to be the problem. However, I'm not suer if
<BR>
the 1200UB backend will work when the scanner is detected correctly by
<BR>
the scanner module.
<BR>
<P>Bye,
<BR>
