Hi,
I'm working on getting a RS232 scanner working on Linux. I see that
Sane has some support for serial port scanners but not much. The
scanner is attached to a POS system for retail sales and runs RHEL5.
Unfortunately, I have no documentation for the scanner, I'm not even
sure of the brand.
i have quite a bit of omr experience, and have done a bit with rs232
in the past, but never scanners. do your logs show the actual data
being passed? if so, i think your first effort should be to extract
image from logs.

Hi,
I think it's a bit simpler than that. The diagnostic software shows an
array showing the marked boxes. Here's what I get form the
diagnostic software when I scan a slip:
Please select:
Ticket count: 1
ticket data len=52
.. 1 2 3 4 5 6 7 8 9 0 A B C D .. 1 2 3 4 5 6 7 8 9 0 A B C D
1 * * * .
but is this diag software output post-processed by the pc? if you have
logs of the data in flight, and there is no image, then you dont need
sane, you need a standalone app.

Hi,
Thanks for your comments.
I don't think that there is an image - the log file for the ltrace
output is only ~40kb. I think that the scanner is returning the array
and there is no post-processing by the diagnostic application.
The scanner is also capable of returning an image of the scanned
Hi all, sorry this is such a long post.
It was a problem but I fixed it before asking for help by swapping the
usb connection back to the old USB 1.0 port Anyhow in case you might
be interested below is what I was going to send.
I still don't understand why /proc/bus/usb is empty though.

the scanner and work out what is happening.

the sane driver :)
Not quite. I was hoping that the

Hello!!
We have maded a big frame (lika a door) with rail for the ccd's of the
scanner.
We take some test with the motors. Now we need try two scanner in
parallel.
It's possible to setting xSane to start two scanner at same time? How?
What i need about softwares? I'm on Ubuntu with xSane ecc.
I am new to the Linux world (via Ubuntu 8.04) and like most of what I am
experiencing. However, there is a lot to learn in the transition from
Windows XP.
I was pleased to see that Ubuntu came with Xsane preloaded and that
Xsane fully supported my Epson Perfection 2450 Scanner. However, I soon
you should not need anything other than libsane and xsane installed to
get scans. the ICM type stuff is useful for color correction, but is
not required to get color scans.
try this at the command line:
scanimage --mode=color test1.pnm
and then look at test1.pnm and see if it looks correct.

A SANE image is a rectangular area. The rectangular area is
subdivided into a number of rows and columns. At the intersection of
each row and column is a quadratic pixel. A pixel consists of one or
more sample values. Each sample value represents one channel (e.g.,
the red channel). Each
that case, the configuration files are below /usr/local/etc/sane.d/.
If you want them where your distribution put them, you need to rebuild
and reinstall after running
./configure --sysconfdir=/etc
Hope this helps,

- replace linux specific ppdev code with sanei_* equivalent functions.
- make sure the code is still compatible with latest SANE releases (in
this case, it is better to check code from Debian's
sane-backends-extras, for which Julien has made a great job making the
code at least compilable for
$ scanimage

There may be a status of some kind I can check from SANE without
crashing before I try scanning but I haven't found
