<P>
As indicated in the title, I'm trying to use a Snapscan 1212u with SANE.
<BR>
Near as I can tell, I don't need the firmware upload utility, but have
<BR>
tried it just in case. I came to this conclusion by running the
<BR>
agfafirm script in verbose mode. I noticed that the scanner reports a
<BR>
firmware before attempting to load the firmware. The output lists the
<BR>
following from the scanner:
<BR>
<P>Vendor: AGFA
<BR>
Version: 1.10
<BR>
Model: SNAPSCAN 1212U
<BR>
Firmware date: THU AUG 06 1998 10:35
<BR>
<P>Now, as I'm reading this information from the scanner (at least I'm
<BR>
pretty sure I am), I'm fairly certain that I've got the right USB driver
<BR>
loaded and am working with the right device. I'm using the scanner.o
<BR>
from the 2.4.6 kernel sources and using /dev/usb/scanner0.
<BR>
<P>I've tried loading the firmware just incase, but I'm fairly certain that
<BR>
this is failing. The verbose output for the file firmware lists:
<BR>
<P>Chip: 7107U
<BR>
Vendor: AGFA
<BR>
Version: 1.32
<BR>
Model: SNAPSCAN 1212U_2
<BR>
Firmware date: MON Jul 12 1999 19:00
<BR>
Size: 30906
<BR>
<P>The script indicates that the load finished:
<BR>
<P>Uploading new firmware...
<BR>
Done!
<BR>
<P>But, then appears to be unable to retrieve the firmware information from
<BR>
the scanner:
<BR>
<P>Vendor:
<BR>
Version:
<BR>
Model:
<BR>
Firmware date:
<BR>
<P>Also, at this point there is an error in my system log:
<BR>
<P>scanner.c: read_scanner(0): Failure to clear endpoint halt condition
<BR>
(0).
<BR>
<P>Sorry if this is a frequently asked or answered problem, but I can't
<BR>
seem to get the scanner to work. I've compiled the sane backend v1.0.5
<BR>
with the snapscan-20010411 patches.
<BR>
<P>I've tried running &quot;scanimage -L&quot; which blocks for quite some time,
<BR>
during which I get the following messages in my system log over and
<BR>
over:
<BR>
<P>usb_control/bulk_msg: timeout
<BR>
scanner.c: write_scanner: NAK received.
<BR>
<P>Anyone got any ideas?
<BR>
<P>Jamin W. Collins
<BR>
<P>BTW, the scanner does work with the manufacturer provided software under
<BR>
Windows.
