SANE (Scanner server) - Any chance for WL-500g?

[PCTV]

unfortenatly, either sane-find-scanner and scanimage -L found the scanner...

I suggest, that You first try to get a running sane/xsane on some linux box. Eventualy You could also try virtualbox or some vmware-server product that is free. Try USB key to prove USB functionality. Then proceed with scanner.

I found this HowTo and aparentely the printer and scanner should work with the sane-backend we are using on Oleg firmware...

http://gentoo-wiki.com/HOWTO_EPSON_C..._configuration

Do we have any kind o debuging or logging we can activate to determine why the scanner is not being found?

Activated some debug flags and got the following return from scanimage -T

[dll] sane_init: SANE dll backend version 1.0.12 from sane-backends 1.0.18-cvs
....
[dll] load: searching backend `epson' in `/opt/lib/sane'
[dll] load: trying to load `/opt/lib/sane/libsane-epson.so.1'
[dll] load: dlopen()ing `/opt/lib/sane/libsane-epson.so.1'
[dll] init: initializing backend `epson'
[dll] init: backend `epson' is version 1.0.247
[dll] sane_get_devices: found 0 devices

From the info on http://www.sane-project.org/sane-mfgs.html#API i believe we need a more recent backend like the one (libsane-epson.so.1.0.4) i found on this site http://khk.net/sane/news.html

How can i deploy it? Is just a copy to /opt/lib/saned ? What configuration changes should be done?

I also found this one http://khk.net/sane/download.html but i don't know how to compile it... Can anyone do it, please?


Thanks in advance,
PCTV

I use 1.9.2.7-9 Oleg Firmware on Asus wl-500gP
My Printer-Scanner is HP LJ M1120 MFP
Printer work Excellent, but scanner didn't

I setup all like in alex_g's post
Version of sane is 1.0.19+cvs from repository

'sane-find-scanner' output:

  # 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".

found USB scanner (vendor=0x03f0, product=0x5617) at libusb:003:002
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program. 

'scanimage -L' output

device `hpljm1005:libusb:003:002' is a Hewlett-Packard LaserJet M1120 multi-function peripheral 

But 'scanimage -T' command tell me this:

scanimage: can't resolve symbol 'round' 

When use scanner through network, all windows sane frontends is hanging.
Saned process on router is starting and finish shortly.

i don't know what to do next.
Can the scanimage message be an error in source of sane?

[karlson911]

I additionaly search sane sources for 'round' and found this in 'hpljm1005.c' file

/*
 * List of pointers to devices - will be dynamically allocated depending
 * on the number of devices found. 
 */
static SANE_Device **devlist = NULL;

static void
update_img_size (struct device_s *dev)
{
  int dx, dy;

  /* Only update the width when not scanning, 
   * otherwise the scanner give us the correct width */
  if (dev->status == STATUS_SCANNING)
    {
      dev->height = -1;
      return;
    }

  dx = dev->optionw[X2_OFFSET] - dev->optionw[X1_OFFSET];
  dy = dev->optionw[Y2_OFFSET] - dev->optionw[Y1_OFFSET];

  switch (dev->optionw[RES_OFFSET])
    {
    case 75:
      dev->width = round ((dx / ((double) MAX_X_S)) * 640);
      dev->height = round ((dy / ((double) MAX_Y_S)) * 880);
      break;
    case 100:
      dev->width = round ((dx / ((double) MAX_X_S)) * 848);
      dev->height = round ((dy / ((double) MAX_Y_S)) * 1180);
      break;
    case 150:
      dev->width = round ((dx / ((double) MAX_X_S)) * 1264);
      dev->height = round ((dy / ((double) MAX_Y_S)) * 1775);
      break;
    case 200:
      dev->width = round ((dx / ((double) MAX_X_S)) * 1696);
      dev->height = round ((dy / ((double) MAX_Y_S)) * 2351);
      break;
    case 300:
      dev->width = round ((dx / ((double) MAX_X_S)) * 2528);
      dev->height = round ((dy / ((double) MAX_Y_S)) * 3510);
      break;
    case 600:
      dev->width = round ((dx / ((double) MAX_X_S)) * 5088);
      dev->height = round ((dy / ((double) MAX_Y_S)) * 7020);
      break;
    case 1200:
      dev->width = round ((dx / ((double) MAX_X_S)) * 10208);
      dev->height = round ((dy / ((double) MAX_Y_S)) * 14025);
      break;
    }
    
    DBG(2,"New image size: %dx%d\n",dev->width, dev->height);

} 

May be i lack some type of program from repo to solve this trouble?
anybody knows?
thnx

Try

LD_TRACE_LOADED_OBJECTS=1 scanimage -T 

and post output here.

I still can't bring to work Sane with my HP LJ 1120 MFP

I think i should rewrite 'hpljm1005.c' without 'round' function, and then recompile sane.

Maybe error 'scanimage: can't resolve symbol 'round' appears because of bad or old system librarys (uclibs, glibc or something else) but all my movements to resolve this didn't lead to success.

Hello all,

Sorry to dig up this old thread but it seemed the most appropriate one for my questions...........
I have an ASUS WL520GU & Epson Stylus CX3100 printer-scanner
Stock Asus firmware does not detect my Epson.
BTW, all linux distros detect CX3100 & I can use both printer +scanner with no problem at all.
I flashed the firmware to ddwrt.v.24_mini_generic & followed their wiki to add usb base drivers, printer, & scanner. In the end I managed to get printer working (but there is no info on the web UI about my printer). The info on the wiki about scanner is practically nothing (I only picked "ipkg -force-depends install kmod-usb-scanner) but still I managed to do "insmod /jffs/lib/modules/2.4.30/scanner.o" and "dmesg | grep usb" showed some info about scanner.
Google leads me to this thread & "ipkg -force-depends install xinetd" is a success but ipkg can not find sane-backends.

Then I flashed to Oleg firmware wl520gu-1.9.2.7-10.trx. Web UI detect my printer & I can use it (wired or wireless) with no problem at all.

My questions are:
- is the procedure indicated on page 2 of this thread still valid & can be applied to the firmware version that I am currently using??
- is there still any space left in my 4MB router? oleg fw = 3.6MB with usb storage, printer, camera,etc... vs ddwrt_mini= 2.8MB with no USB at all

Of course, it would be best if somebody can write up a new detail howto.
But still some leads and clues are highly appreciated as well

Thank you

[oleo]

Sane backends are available for oleg and dd'wrt firmware through Nslu2 Optware feeds. It should work if your scanner is supported. With additional USB key for software, maybe.

[PanDor]

Greetings. Has read, but has not understood, how to me to connect the scanner to Asus wl-500gp? Help. Stick with a nose.

[dccharacter]

Hi all, thanks for the thread. Trying to follow, but the scanner simply would not mount.

Oct 23 23:58:34 kernel: usb.c: registered new driver usbscanner
Oct 23 23:58:34 kernel: scanner.c: 0.4.16:USB Scanner Driver
Oct 23 23:58:34 kernel: scanner.c: probe_scanner: User specified USB scanner -- Vendor:Product - 924:4265

What I'm missing here is a row that says "mounted to scanner0".

sane-find-scanner sees the MFD (Xerox 3119), but scanimage -L wouldn't work.

Possible reasons:
1. I put my username in the xinetd config, but ommited group (simply don't know how to find out what it should be)
2. Xerox 3119 is not supported by Sane (however I saw people working with it in Ubuntu)

If you know what's the problem, thanks in advance for helping me here. Best.

Hi everyone!
Could somebody give me correct /opt/etc/xinetd.d/saned file for samsung 4200 ?
Right now I have this one

service saned
{
port = 6566
socket_type = stream
server = /opt/sbin/saned
protocol = tcp
user = root
group = root
wait = no
disable = no
}

But it's incorrect, because of errors

Can anyone help? =(
