Downgrading/upgrading
===================

@Lucio: No, downgrading didn't solve the problem for me either.

I had another semi-similar problem (with cups-pdf) and another guy told it solved it by uninstalling/reinstalling.
I had already done that with sane and it didn't solve my problem.

So I tried to dowgrade, and it didn't solve it either.

So I decided to upgrade back and the scanner happened to work.

Firmware
=======

Be careful, though, because it seems that the path where saned searches the firmware had changed.

For me, in the config file /etc/sane.d/artec_eplus48u.conf, I had to fix the line:
 option artecFirmwareFile /usr/share/sane/firmware/Artec48.usb

because the firmware really was located at:
option artecFirmwareFile /usr/share/sane/artec_eplus48u/Artec48.usb

udev rules
========

To have access to the device as a normal user, you have to inform the device manager about the permissions you want to find on your device.

The USB devices are identified by 2 fields : the vendor one and the product one. A lsusb command gives you both with the form XXXX:YYYY (XXX being the vendor one, in my case, 05d8 and YYYY the product one, for me 4009).

I decided to give my scanner the 0664 permissions, so that any memeber of the group "saned" might be able to write commands to the scanner.

@larytet: I'm afraid I can't be more explainful - hope this is good for you
