Hi. I've been trying to set up scanner Canon Lide 110, so far unsuccessfully (even after reading some posts, which got me rather confused...)

The scanner is listed among supported devices on the SANE website. Moreover, back then I managed to get the scanner working with Ubuntu, but cannot remember how I did it ever since (I'm quite sure I forget to do something essential). Now I use CrunchBang.

I'm not quite sure what all information I should post, but I guess this would be it for the beginning...:

(Did the same as root, the results were the same.)


I would be grateful for any help. Thanks.

Two things to look at.

1. With the scanner turned on, and plugged into a usb port, have a look at the /dev directory to see if the device shows up there. I have a HP scanner that uses the genesys backend, the same backend that supports your Canon scanner. On my system I see this:

If the device is not showing up, in the /dev directory, it will not work.

2. Have a look at the file /etc/sane.d/genesys.conf file, look to see if your scanner is uncommented. It should look like this:

1) The device doesn't show up in there. (Even after following.)
2) Well, the scanner wasn't even listed.

Thus I figured I hadn't even the sane-backends installed ^^; (I somehow expected it would do so, er, itself.) // Following these instructions... http://mp610.blogspot.cz/2008/04/giv...shly-sane.html
Had to install libusb-dev as well.
Also had to add myself in the "scanner" group.
... copied this file, because the scanner wasn't listed:
The situation is still the same as in the beginning, though.

Do you have "usb-utils" installed?

Yes, I do.

Does Crunchbang not have a package called sane? This should have the genesys backend your scanner needs. The one you listed is for Pixma scanners.

It does - I installed it as the very first already.

I went to canon driver downloads they don't have linux drivers

I see. Anyway, on my other laptop with Ubuntu the scanner works without a flaw. Now I even installed newer sane-backend and reinstalled everything else, but still no luck.
Oh, and the scanner still doesn't show up in the /dev directory.

One more question - by what is it probably caused? Is there some other way I could get the scanner to work? I'm considering purchasing another scanner if the situation won't change.
Thanks.

It will not matter what backend and frontend you have installed if the scanner doesn't show up in /dev. The system needs a file here to talk to any device.

What type of connection does the scanner have? usb, parallel port, serial?

USB.

With the scanner plugged in and turned on, post the output of the command 'lsusb' ( without the quotes ).

You have a /dev file, somewhere. The scanner would not show up with lsusb without the file.

I have a canon Pixma 240 & although they used to support linux they never updated their printer drivers for linux. So I gave up on trying to install them & just use my hp printer which was plug & play in Debian.
