I have a Kyocera Taskalfa 1800 MFP which I am configuring as a
scanner which is not working in any linux distro (tried with Ubuntu,
Fedora, Arch Linux and Debian), although the printer is working
fine. Although sane website is showing nothing like this printer I
have downloaded the sane library for scanner from the official
website but whenever I try to run scanner (using scanimage or
xsane), the printer awakes and the program (or command) shows the
error scanimage: open of device kyocera_gdi_a3:libusb:001:019
failed: Invalid argument.
The things I have already tried are, tried changing the permission
of the library in sane (libsane_kyocera_gdi_a3) as well as usb
manually and through udev. I have tried to debug using
SANE_KYOCERA_GDI_A3=255 scanimage
with no success.
OK I have installed their package. I have Linux Mint, so Ubuntu-based
distro.
It seems to install correctly and the 2 backends (kyocera and
kyocera_gdi_a3) seem to be loaded up. You can test this with
SANE_DEBUG_DLL=3.
Diag from the backends can be got with SANE_DEBUG_KYOCERA and
SANE_DEBUG_KYOCERA_GDI_A3:

Obviously I don't see anything detected because I don't have one of
these devices.
Not really sure what the difference between these two backends is or
which one is expected to work with your device.
Perhaps you could try generating some diag output from their backend
when attempting to scan?
Cheers,
Ralph
