[sane-devel] CANON Canoscan 9000F - FAIL Error: Error during device I/O

[Ales Mateju]

Hi, I try to install scanner CANON Canoscan 9000F Mark II via USB under OS 
linux Ubuntu 12.04.LTS 64k. After scanimage -T I get  error FAIL Error: 
Error during device I/O. Other frontends ( xsane, gimp) says that I/O error 
appeared as well. Can somebody help me what to do next? Thanks Ales.

I did this steps:
- uninstall old version
- install new version 1.0.27
- create link
BACKENDS=pixma ./configure --prefix=/usr  --localstatedir=/var --sysconfdir=
/etc
sudo make instal
sudo ln -i -s /usr/lib/sane/libsane-pixma.so.1.0.27 /usr/lib/x86_64-linux-
gnu/sane/libsane-pixma.so.1
- after sudo find / -name "libsane-pixma.*" I get
/usr/lib/x86_64-linux-gnu/sane/libsane-pixma.so

I get this results:
- sane-find-scanner can find my scanner - the second one

- scanimage -L can find my scanner

- scanimage -T  get I/O error

scanimage: acquiring RGB frame, 8 bits/sample
scanimage: reading one scanline, 1914 bytes...    FAIL Error: Error during 
device I/O
- scanimage -V get mismatch of versions
scanimage (sane-backends) 1.0.27; backend version 1.0.22
- other frontends ( xsane, gimp) can find scanner but get I/O error

from debugger lists it looks like ...
- from SANE_DEBUG_DLL=255 scanimage -L it looks that system can find correct
version of backends at right place and can load it 
[dll] load: searching backend `pixma' in `/usr/lib/x86_64-linux-gnu/sane:/

- SANE_DEBUG_DLL=3 scanimage -T gives more information about sane_init. I am
not sure that it is important for loading of wrong backends version  
[dll] sane_init: SANE dll backend version 1.0.13 from sane-backends 1.0.22
[dll] sane_init/read_dlld: using config directory `/etc/sane.d/dll.d'

at the end
1/ I am not sure I understood well the current state
2/ I don't know what to do next. Try to looking for mistake in my 
instalation of backends or try to check instalation and configuration of 
frontends and how, ...
3/ ... or looking for other mistake
