Canon CanoScan LiDE 120 driver

[Zelator57]

http://www.sane-project.org/sane-mfgs.html#Z-CANON shows this as supported, as does http://www.sane-project.org/sane-bac...html#S-GENESYS, but it is not in file:///usr/share/doc/packages/sane-backends/sane-mfgs.html#Z-CANON.

~> sudo sane-find-scanner
found USB scanner (vendor=0x04a9 [Canon], product=0x190e [CanoScan], chip=GL848+) at libusb:002:003

~> sudo scanimage -L finds nothing

~> lsusb shows

sane-find-scanner shows the chip to be GL848+, while the sane-project.org references show GL124+.

How can I install a version of sane-backends that knows about the LiDE 120? Or is there a better way?

I had to research this a bit to check the likelihood of support for this scanner model. The most credible source of evidence for support was found via this Ubuntu thread. There it was suggested that recent SANE backend source code included required support in the genesys backend.

In an effort to assist, I first tried installing the sane-backends-1.0.27 package from the openSUSE graphics repo, but a quick check of the man page for the sane-genesys backend didn't explicitly list the LiDE 120 model, so I then proceeded with building from the latest git source, and that does indeed seem to have the required support explicitly mentioned in 'man sane-genesys'.

git clone git://git.debian.org/sane/sane-backends.git

Change to the directory...

cd sane-backends

and build...

./configure
make
sudo make install

I encountered no problems building the backends. Hopefully you won't either.

Having installed git-core and gcc sane-backends was installed. However the CanoScan LiDE 120 is still not listed in the Yast scanner function.
I un-commented canon in /etc/sane.d/dll.conf to no effect.
The config.log from the installation shows the version as still being 1.0.27:

man:sane-genesys lists only Canon LiDE 35/40/50/60/100/110/200/210/700

BUT http://www.sane-project.org/man/sane-genesys.5.html lists
Canon LiDE 35/40/50/60/100/110/120/200/210/220/700
Should I perhaps be using git://anonscm.debian.org/sane/sane-backends.git? I can see no overt reference to the LiDE 120 there but I am not at all familiar with the development and deployment process.

As the sane project lists the LiDE 120 as supported, either this is a mistake or something has gone wrong somewhere.

Further investigation - in the /home/andy/installs/sane-backends/ installation directory, /doc/descriptions/genesys.desc contains:

It's the genesys backend that needs to uncommented.

I used "git://git.debian.org/sane/sane-backends.git" and the support for the LiDE 120 model is listed in the man page...

DESCRIPTION
The sane-genesys library implements a SANE (Scanner Access Now Easy) backend that provides access to
USB flatbed scanners based on the Genesys GL646, GL841, GL843, GL847 and GL124 chips. At present,
the following scanners are known to work with this backend:

Canon LiDE 35/40/50/60/100/110/120/200/210/220/700

However, that's as far as I can go as I don't have the Canon device to test with.

As the sane project lists the LiDE 120 as supported, either this is a mistake or something has gone wrong somewhere.

The SANE page for 1.0.27 did list the device but it referenced a different (GL124+) ASIC chip. They may need contacting about that.

The canon.desc (description) relates to a different driver (for differenct Canon models). The genesys driver is what's relevant here.

genesys is already uncommented in /etc/sane.d/dll.conf.

for me man:sane-genesys shows only
Canon LiDE 35/40/50/60/100/110/200/210/700.

There seems to be a disconnect somewhere.

I'll follow up on that link.

Thanks for your help.

Some parts of this seem to know about it but not all. Once my subscription to the sane-devel list is activated I'll try them with it.

[V_ido]

If you can not try it Vuecsan https://www.hamrick.com/download.html
And install libusb-0_1-4

[Zelator57]

Partial success with Vuescan. Though I would prefer to have Xsane working for the new LiDE 120, or at least the old MG2500. As things stand I could pay for Vuescan, use the MG2500, and hope sane gets sorted out over the coming months.

I installed Vuescan, but their documentation says that for the Canon LiDE 120 I need to set up libusb device protections.
Several sources give risky-looking solutions, but:
http://rglinuxtech.com/?p=1659 UDEV – Getting an Old Scanner to Behave..
seemed less traumatic, adding a ‘.rules’ file under the /etc/udev/rules.d directory.

~> lsusb |grep Canon
Bus 002 Device 004: ID 04a9:176d Canon, Inc.
Bus 001 Device 006: ID 04a9:190e Canon, Inc.

(04a9:176d is an mfp - low quality scanner)

Created 82-canon_lide120.rules -

# Canon LiDE 120
ATTRS{idVendor}=="04a9", ATTRS{idProduct}=="190e", ENV{libsane_matched}="yes", GROUP="users", MODE="0664" (also tried 666)

Is that ENV{libsane_matched}="yes" a problem? As sane obviously doesn't know about it.

Vuescan finds both scanners, but only the mfp 04a9:176d produces an image, 190e does a pass of the document but the light is not on. Blank image with watermarks only.

Xsane and Scanlite only find my MS webcam and try to use that. Scangearmp finds no scanner.
