[sane-devel] Samsung SCX-3205W not working

[Дмитрий]

For Samsung SCX-3205W driver needed xerox_mfp. So write all the internet.

The device is connected, the printer works.
# 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.

found USB scanner (vendor = 0x04e8 [Samsung Electronics Co., Ltd.], 
product = 0x3441 [SCX-3200 Series]) at libusb: 001:003
   # 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.

As if the scanner finds.

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).

There is scanner.

Then add a line in the file / etc / sane.d / xerox_mfp.conf:
usb 0x04e8 0x3441

And in the file / etc/udev/rules.d/25-libsane.rules in the relevant 
section added:
ATTRS {idVendor} == "04e8", ATTRS {idProduct} == "3441", MODE = "0664", 
ENV {libsane_matched} = "yes"

# Service udevd restart

Check:
# Scanimage-L

All online writing that should work, but I have in any ...

/ Usr/lib/sane/libsane-xerox_mfp.so.1.0.22
/ Usr/share/man/man5/sane-xerox_mfp.5.gz

I decided to check out what makes scanimage-L
# Strace-o / tmp/1.txt scanimage-L

After reviewing the file, get the following .. scanimage opens the file 
/ etc / sane.d / dll.conf, through all that is there. For simplicity, 
the experiment I just left dll.conf xerox_mfp .. Linke Board of Rites / 
usr/lib/sane/libsane-xerox_mfp.so.1, then collects all of the Old / sys 
/ bus / usb / devices including / sys/bus/usb/devices/1-1 / (vendor_id 
here = 04e8 and product_id = 3441), then open the file / etc / sane.d / 
xerox_mfp.conf and issues that do not have the scanner ...

Prompt please where to dig.

Thanks...

Для Samsung SCX-3205W нужен драйвер xerox_mfp. Так пишут все интернеты.

Устройство подключено, принтер работает.

Как бы сканер находит.

Нет сканера.

Тогда добавляю строку в файле /etc/sane.d/xerox_mfp.conf:
usb 0x04e8 0x3441

А в файл /etc/udev/rules.d/25-libsane.rules в соответствующий раздел 
добавил:
ATTRS{idVendor}=="04e8", ATTRS{idProduct}=="3441", MODE="0664", 
ENV{libsane_matched}="yes"

# service udevd restart

Проверяю:
# scanimage -L

Все интернеты пишут что должно работать, а у меня ни в какую...

/usr/share/man/man5/sane-xerox_mfp.5.gz

Решил проверить что же делает scanimage -L
# strace -o /tmp/1.txt scanimage -L

Изучив файл, понял следующее.. scanimage открывает файл 
/etc/sane.d/dll.conf, перебирает все что там есть. для простоты 
эксперимента я в dll.conf оставил только xerox_mfp.. Линкует либу 
/usr/lib/sane/libsane-xerox_mfp.so.1, затем собирает всю инфу из 
/sys/bus/usb/devices в том числе и /sys/bus/usb/devices/1-1/(тут 
vendor_id=04e8 и product_id=3441), после этого открывает файл 
/etc/sane.d/xerox_mfp.conf и выдаёт что нет сканера...

Подскажите пожалуйста куда копать.

Спасибо.
