[sane-devel] Xsane/scanimage -L only works as root
Hello, I have Mandriva 2007 with an HP Photosmart C3180 All-in-One device. The printer part works well (with the HP drivers) I would like to use the scanner function with Xsane (I tried it on Ubuntu and it worked), but it only works as root. With normal user the device is not detected. Even scanimage fails as a normal user: renan@wizard:~$ scanimage -L No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages). But with root it work: renan@wizard:~$ su Senha: [root@wizard renan]# scanimage -L device `hpaio:/usb/Photosmart_C3100_series?serial=BR6BIGN0NR04KV' is a hp Photosmart_C3100_series multi-function peripheral I think it might be a permission problem. If so, what files should I change permission/ownership of? Thanks! Renan Birck -- next part -- An HTML attachment was scrubbed...

Well, before making any real patch, the first thing I'd like to

Seems that the Suse folks did not trust the usage of the HZ macro
that much. IIRC, HZ gives something like the kernel-internal timer
resolution or similar, and specifiying this value outside a header
file make some sense.
Since 2.6, the kernel runs with two timer resolutions, one for the
internal accounting, which is in general 1000Hz - 1ms and the other
one having a 4ms = 100Hz resolution (the default). The later one is in
general reflected by the HZ, that is used in the scsi lib.
While doing some cross-compilation stuff, I've already seen this
sysconf stuff, so it should be save to use it. Could you please
check the attached patch? (It's borrowed from gdb code)
Compiling sanei_scsi.c from sane-backends 1.1.18 with this patch
instead of the added #include line works fine.
That's what I've expected ;)

When I compiled the sane-backend the include-file seemed to be unread:
sanei_scsi.c:1276: error: 'HZ' undeclared (first use in this function)
In addition, it only was defined for 60 Hz:
#define SG_DEFAULT_TIMEOUT (60*HZ) /* HZ == 'jiffies in 1 second' */
(/usr/include/scsi/sg.h line 268)
therefore I added a line to fix HZ on 50, and then installed the backend
without further problems.
Also sane-frontends installed fine.
The scanner was not recognized however. Starting xsane I got the message
no devices available with 6 possible reasons under help:
- device not supported by sane? Thought epson 2580 is supported
- supported device is busy No, it isn't
- no permissions, try as root Did not help
- back-end is not loaded by saneAdded usb 0x4b8 0x121 to
/etc/sane.d/epson.conf and thinkthis
defines it properly
- back-end not configured properly Answered on other back-end point
- possibly more than one sane-version No there is not.
installed.
My question: anyone a suggestion how to get my epson 2580 recognized?
Thanks

This patch replaces the fixed HZ compile-time value (which is
no longer supported by new glibc) by the more correct
sysconf(_SC_CLK_TCK) runtime value because a fixed HZ compile-time
value may be wrong in the running system if the runtime system
is not exactly the same as the compile-time system:

Greetings; I have been trying for a few weeks to compile the cvs feed with no luck. I have the 2.6.18 kernel and Slackware. My libc is 2.3.6.

[sane-devel] How to use Dextra Scanner DF-1200+ with sane-teco1
Hello SANE-Experts, I am trying to get my oldie Dextra scanner to work with Linux and SANE ubuntu6.10 (2.6.17) - sane-backends-1.0.18 With scanimage --mode Grayscale scanning works fine - output-sheet ok. The problem: scanimage --mode Colorscanning works for all three passes R,G,B but the output-sheet colors are wrong - blue fails, no error messages detected. Then I look with a hexeditor into the output.png file - all data bytes for the Blue-channel = 00 ,Red and Green-channel data ok. (The Scanner itself is ok, works in colormode with twain/Win98) cat /proc/scsi/scsi Host: scsi0 Channel: 00 Id: 04 Lun: 00 Vendor: Dextra Model: DF-1200+ Rev: 1.03 Type: Scanner ANSI SCSI revision: 02 scanimage -L device `teco1:/dev/scanner' is a Relisys AVEC Colour 2412 flatbed scanner FCC-ID:E80VM3520 How can I use these untested Scanner with sane-teco1 ?

I would say that it is not the right kind of environment to go making people to get an account on the machine; they should be able just to come and run the scanner. I would say that it should not be permissible to run any shell (by, for example, launching an xterm with a command prompt) and also it would be good to set up xsane so that it automatically clobbers the previous output file when a new scan is done, and the user who walks up to the machine cannot change that. Also, the save-the-file dialog should only allow the file to be saved in the scanner account's directory, or on the flash drive (which would require a hookup of the save-file dialog to mount the flash drive automatically and invisibly, but with a warning in case it has been attached, and to unmount it when the file has been copied, along with another warning if said flash drive is removed prematurely). Furthermore, the save-file dialog should only allow inspection of the scanner home directory and of the flash drive, not other directories. Has anyone already done something like this? To what extent is it possible to configure xsane by means of an .rc file, which the user cannot alter? Also, how difficult would it be to get the Help key to give some help which is specific to the situation, telling the user what can and cannot be done, and how to do what can be done? I have figured out how to do things like set up an account which will start X straightaway and will then do nothing but to run xsane, or perhaps a TCL menu box which will do nothing but offer certain options. But how much of what I want could be done inside of xsane, with custom configurations, without a major overhaul of source code? Theodore Kilgore
