<P><EM>&gt; Hello,
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; rumours say, that HPs S20 photo scanner supports SCL, but the firmware
</EM><BR>
<EM>&gt; must be loaded from disk first. Is there someone on the list who has
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; a) a S20 scanner
</EM><BR>
<EM>&gt; b) another working USB scanner under Linux
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; to do some tests ? Boot windows and initialize the S20. Reboot to Linux
</EM><BR>
<EM>&gt; without
</EM><BR>
<EM>&gt; switching off the scanner and try SANE with the HP-backend on the S20.
</EM><BR>
<EM>&gt; I would be interested if that is working. Could be a first step to
</EM><BR>
<EM>&gt; support the S20.
</EM><BR>
<P>Hi,
<BR>
<P>I have a S20, but no other USB scanner - I can't tell whether I
<BR>
set things up correctly. Here's what I did:
<BR>
<P>&nbsp;&nbsp;modprobe usbcore
<BR>
&nbsp;&nbsp;modprobe usb-uhci
<BR>
&nbsp;&nbsp;insmod /lib/modules/current/misc/scanner.o vender=0x03f0 product=0x0102
<BR>
&nbsp;&nbsp;mount -t usbdevfs none /proc/bus/usb
<BR>
<P>hp.conf says:
<BR>
&nbsp;&nbsp;/dev/usb/usbscanner0
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;option connect-device
<BR>
<P>the device file:
<BR>
&nbsp;&nbsp;crw-rw-rw- 1 root root 180, 48 Mar 17 19:47 /dev/usb/usbscanner0
<BR>
<P>When I now try to start xsane or xscanimage, it will hang for
<BR>
about a minute, eating all available CPU time. The syslog says:
<BR>
<P>&nbsp;&nbsp;swamp kernel: usb_control/bulk_msg: timeout
<BR>
&nbsp;&nbsp;swamp kernel: scanner.c: read_scanner(0): NAK received
<BR>
<P>When I unload the scanner module, xsane works as usual again
<BR>
(I also have a UMAX SCSI scanner)
<BR>
<P>Regards,
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Peter
<BR>
