backend required for Genuis scanner

[Member roland]

I had a Genius ColorPage-Vivid 3XE USB scanner given which I would like to use with 16.3 on a 64-bit PC, fully up to date. I understand I need to install a backend to permit this. Simple Scan recognises the device correctly but an attempt to scan results in Failed to Scan – Unable to connect to scanner. I have tried variations on all the options offered by Simple Scan to no effect. However I am certain the scanner is connected ok and is in working order. Can anybody advise if the correct backend comes with 16.3 and if so what should I do to install it?

Thanks in advance

1. run simple-scan -d
2. perhaps you should try a downgrade, too. However, it’s RISKY for your whole system

with all the trial and errors, I guess inmy case it is a problem of the USB driver/library

Maybe it’s the same problem, but maybe not.
Please try
sudo usermod -a -G scanner YOURUSERNAME
newgrp - scanner

This will add your user to the scanner group, if it isn’t already.Replace YOURUSERNAME with yours.
Did you already try to run simple scan as root ?

sane-utils should be installed by default, if not please install it and post the output of
sane-find-scanner
scanimage -L
Maybe that gives hints what’s wrong.

Reading through SANE material this module is suggested as a suitable backend – ccd548.fw – any comments please?

Please find attached the results of the suggested trials. Even though simple scan fails to find any scanner it has the correct scanner name on line 1 op the options panel when selected so the scanner appears to be recognised.

I usually get tripped up by failing to convert files to pdf before attaching, sorry about that.

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane­find­scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Looks like you are right, you need the ccd548.fw – backend.
http://www.meier-geinitz.de/sane/gt68xx-backend/
There are some How Tos to set it up and extract the file if you have a windows-installation with the driver.
https://help.ubuntu.com/community/GeniusColorpageVivid4X
The only one to download I could find is here.
http://www.escomposlinux.org/fer_y_juanjo/ccd548.html
You have to install sane on antiX , follow the instructions where to move the file.
Some reported success , some not by doing this.
