xsane queries

Ganapati Hegde — 2012-05-25T13:55:29

Hi Oliver ,

 

I have few queries regarding xsane , I would be of great help if you can
give some valuable inputs on this.

 

In the investigation phase for a new scanner driver that would like to
leverage the XSane application, 

1.Does the vendor have a mechanism of disabling unsupported
features in existed xsane
2.If the vendor wants to add a feature, is there a config file
that you can modify without actually modifying code. Hence each vendor
will not disturb other installations.

If not, would XSane consider adding/disabling unsupported features?

3.And how do we submit our changes? 
4.What is the mode of deployment for our scanner driver frontend ?
Is it through XSane updates, or can we ship the same externally through
an installer.

 

Regards

Ganapati Hegde

scanimage -L has stopped working,sane-find-scanner still detects

Bryan McNeil — 2012-05-24T17:56:22

I'm running mac osx 10.7 and originally was set up using the packages
available here: http://www.ellert.se/twain-sane/ (libusb, sane backends,
twain sane interface). My scanner was being detected fine last week, since
then I installed drivers for a different scanner (No way that caused this
problem I imagine) and configured, and make install'd the libusb source.
After that scanimage -L was no longer working, but sane-find-scanner still
found the device. The result for that is: found USB scanner (vendor=0x04a9
[Canon], product=0x2220 [CanoScan], chip=LM983x?) at
libusb:001:002-04a9-2220-ff-00. I've tried reinstalling those pakcages
again with no success. Searching around on this archive I found someone
with a similar problem who fixed it by configuring and make installing his
sources again but that has not worked for me.

Any help would be appreciated, thanks.

FW: [xsane-devel] Adding new product

Ganapati Hegde — 2012-05-24T11:11:56

Hi Oliver ,

I was looking into the xsane source code. I would like to know whether
any changes to xsane will be integrated?

      For the new product that I am looking at, I will have to remove
support to some of the existing xsane features for example 'gamma
widgets' as well as some of the options under 'File, Preferences etc'.
Also I will be adding couple of new product specific feature to the
frontend "xsane". Will these changes be integrated into the Xsane
release? If not kindly let me know how do we write new frontend that can
use the sane-backend?

 

Regards

Ganapati Hegde

The author of XSane is not a member of the sane project. You would have
to ask him about how he accepts patches. But I doubt he will remove

Ganapati Hegde — 2012-05-23T12:27:57

Hi,

 

 I have some more questions on the way releases and changes are handled.

 

1.       I was looking into the xsane source code. I would like to know
whether any changes to xsane will be integrated?

a.       For the new product that I am looking at, I will have to remove
support to some of the existing xsane features for example 'gamma

release? If not kindly let me know how do we write new frontend that can
use the sane-backend?

 

2.       Once backend code is submitted how many days will it take for
release to happen, and when will the new backend version be available in
SANE repository. 

 

3.       Will the releases for frontend and backend happen at the same
time?

HP ScanJet 5590 big endian

Nhan Ngo Dinh — 2012-05-22T16:27:57

Hello,

I've been trying to connect an HP ScanJet 5590 to an Atheros AR7241 rev 
1 system (MIPS 24Kc V7.4 CPU), using OpenWrt. The CPU is big endian. I 
got the error:

[hp5590] hp5590_get_ack
[sanei_usb] sanei_usb_control_msg: rtype = 0xc0, req = 12, value = 142, 
index = 32, len = 1

[sanei_usb] sanei_usb_control_msg: libusb complained: error sending 
control message: Connection timed out
[hp5590] hp5590_get_ack: USB-in-USB: error getting acknowledge

Using SANE_DEBUG_SANEI_USB=255 and SANE_DEBUG_HP5590=255 I got exactly 
the same result (even print_buffer() output was the same) as another 
user who tried to use this backend on a PPC (see this post: 
http://lists.alioth.debian.org/pipermail/sane-devel/2010-June/026900.html).

So I tried to run the same device under a little endian platform and I 
saw a difference:

Debugging sane-find-scanner/scanimage

Rogan Dawes — 2012-05-22T14:52:36

Hi folks,

I am using SANE (scanimage (sane-backends) 1.0.22; backend version
1.0.22) on OpenWRT Backfire 10.3.1 on a Buffalo WZR-HP-G300NH,
attempting to interface with a Samsung SCX4300 MFP.

This device is supported by the xerox_mfp backend, and has worked in the
past. Now, for some odd reason, it is failing to detect the scanner.

Here is the debugging output I have managed to obtain:

root< at >gw:/# SANE_DEBUG_XEROX_MFP=128  SANE_DEBUG_SANEI_USB=4
sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make
sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.
  # Also you need support for SCSI Generic (sg) in your operating system.
  # If using Linux, try "modprobe sg".

Ganapati Hegde — 2012-05-16T12:03:35

Hi ,

 

I have a requirement to support new device , How can I integrate  new
product specific backend code with sane and to whom I need to send my
code.

My widgets are different from existing xsane frontend. Can I write my
own product specific frontend code and integrate with sane backend ?

 

Thanks

Ganapati Hegde

updating sane on Ubuntu 12.04 64 bit leaves xsaneusing old sane software

Justin Harding — 2012-05-13T07:59:27

Hi

I have not developed Linux libraries, so there may be something obvious I
missed here ...

I want to use my Canon Pixma MP495 scanner from simple-scan. Sane on Ubuntu
12.04 seems old and doesn't include MP495 support.

After building and installing sane on my Ubuntu 12.04 64 bit system,
simple-scan and xsane were still using old drivers. I fixed this by
updating a link to point to the new sane. Is this correct behaviour?

I built and installed sane as follows

./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
make
sudo make install

After install I had (new drivers are dated 13 May)

Good afternoon,

Yesterday I started setting up my CanoScan 9000F. According to the docs
sane supports this scaner since last year. I compiled the sources for
sane-backend (with libusb) the sane-find-scaner output is the following:

xsane mail settings

Barry Tigner — 2012-05-09T16:47:24

Hi,

There seems to be a name and/or password length limitation of 8 chars
for sending scans to an email account.

I would like to increase this to at least 16 chars and recompile the
current version of xsane. If you can help me find the code that needs
to be changed, I would appreciate it.

In the future , it would be useful if xsane email settings allowed
passwords longer than 8 chars.

Thank you,
Barry

Epson Perfection V200 Photo - scans White as Blue

2cv67 — 2012-05-08T19:19:17

I asked this question a long time ago on Ubuntu Forum, with no result.
http://ubuntuforums.org/showthread.php?t=1576401
Probably this is a more suitable spot?

I have an Epson Perfection V200 Photo scanner.

It works as you would expect in XP, whites come out white, automatically.

In Ubuntu (10.04 thru 11.10) using the flatbed, real whites (white paper 
backgrounds, even the scanner's own white background) come out 
noticeably blue.
This is annoying anyway & especially when printing afterwards.
It is about the same using any of the available Scanner Applications 
(XSane / Image Scan! / Simple Scan / AcquireImages etc.)
See example in above post.

I can roughly correct the problem, once per scanning session, using the 
"Tone Control" in Image Scan! or (much more fiddly) using the "Set as 
White" tool in XSane, but the settings don't 'stick'.

Is there any way to dial this problem out, once & for all, for any or 
preferably all of the applications?

Thanks!

[PATCH] Fix IO error in pixma_wait_interrupt

Daniel Beer — 2012-05-02T20:55:59

I tested commit c4a287e3f28eab0ceb0ef8f0a1d17cb724ad612f with a Canon
MP280 (Linux 2.6.38.5, libusb-0.1.12). scanimage -T failed with an IO
error, which I traced to pixma_wait_interrupt().

This function calls sanei_usb_read_int(). If no data is received, it
returns SANE_STATUS_EOF, which maps to PIXMA_EOF, which is in turn
treated as a fatal error in the calling function.

With the following patch, the MP280 works pretty well. Occasionally an
IO error occurs if you try to scan immediately after power-on
("warming up"?), but it always works on a retry.

As described here:

http://unix.stackexchange.com/questions/36894/hewlett-packard-scanjet-2200c-on-scientific-linux-6-1-64bit

I have a

Hewlett-Packard ScanJet 2200c

scanner connected via USB to my notebook that has Scientific Linux 6.1
64bit OS with the rpmforge repo.

Bus 006 Device 002: ID 03f0:0605 Hewlett-Packard ScanJet 2200c

Scanner plugged in via USB to my notebook.

When I launch this command (no matter that I use it with a normal user
or root, does the same):

scanimage --format=tiff --resolution=150 --mode=color > a.tiff

The scanner just waits for ~30 sec then starts actually scanning, but
it stops after going about ~8cm's.. (so it's scanning just the ~1/3
part of an A/4 paper..) but the scanned part looks good. So the
problem is that why doesn't this scanner scans a full A4 paper size?

I can't find relevant logs..

I wanted to try out the scanner on a Win7Pro64bit machine.. I didn't
found any drivers to it :D

How can I make this scanner work under my OS?

Can anyone help me with this please

avision backend regression issue...

dgronos — 2012-04-30T04:07:41

All,

Upgraded to Ubuntu 12.04.  And was using gscan2pdf when I realized that I
could not scan in any other mode than color.  Previous version, 10.04
Ubuntu, I could scan in all three modes, color, line art & gray scale.
 This does not appear to be the case with the sane-backend 1.0.22
installed.

  Scan mode:
    --mode Color [Color]
        Selects the scan mode (e.g., lineart, monochrome, or color).
    --resolution 50..600dpi (in steps of 1) [150]
        Sets the resolution of the scanned image.
    --speed 0..4 (in steps of 1) [inactive]
        Determines the speed at which the scan proceeds.
    --preview[=(yes|no)] [no]
        Request a preview-quality scan.
