Hi mimosa and galmel
Thanks a lot for the time you spent for all your explanations.
As you said I got rid of the remnants of my previous attempts (packages .deb and .rpm)
After formating the partition and re-installed Salix I´ve installed the alienbob´s packages below
iscan-data-1.36.0-x86_64-1alien.tgz
iscan-2.30.1-x86_64-1alien.tgz
iscan-network-nt-1.1.1-x86_64-1alien.tgz
Now $sudo sane-find-scanner returns
found USB scanner (vendor=0x04b8 [EPSON], product=0x013d [Epson Perfection V39]) at libusb:001:003
and $sudo scanimage -L returns
device `v4l:/dev/video0' is a Noname Built-in iSight virtual device
device `epson:libusb:001:003' is a Epson flatbed scanner
and $sudo scanimage -T returns
scanimage: sane_start: Invalid argument
When opening iscan-data with engrampa I´ve found the file
/usr/doc/iscan-data-1.36.0/SUPPORTED-DEVICES which contains
Epson Perfection V39 (requires iscan-plugin-gt-s650)
What do you think about the installation of this plugin ?
The only plugin I´ve found is iscan-plugin-gt-s650-1.1.0-2.x86_64.rpm

You can repackage the Debian binary, as does Arch:
https://aur.archlinux.org/cgit/aur.git/ ... in-gt-s650
Solus instead builds from source:

Did you follow the post-installation instructions from SBo? galmel gave a direct link to these I think, and also pointed out they will be needed for alienbob's package too. It may also be worth checking there to see if there is anything different required.

I suggest trying this first before following Didier's suggestions if it still doesn't work. But probably, you will still need to perform equivalent steps.

EDIT - something else to try is simply running alienbob's buildscripts with more recent sources, from Didier's link above. To do this, download the source, any other needed files, and the SlackBuild, and edit the latter to correspond to the more recent version number of the source. With any luck, it should build without further modification.

That's a hard step.
iscan-data-1.36.0-x86_64-1alien.tgz
iscan-2.30.1-x86_64-1alien.tgz
If installed in this order, then that's ok.
Now $sudo sane-find-scanner returns

Looks good.
$sudo scanimage -L returns
This call with sudo is not correct. You must call this as an normal user. This is also important because the error messages will be different if errors occur. All normal users who want to use the scanner must be members of the 'scanner' group in /etc/group. So, if your username is 'tux', then at least

Code: Select all

scanner:x:93:tux
must be there.
$sudo scanimage -T returns
scanimage: sane_start: Invalid argument
Sudo here is wrong again. If the call

Code: Select all

scanimage -d test -T
shows no errors, you can continue testing with the call

Code: Select all

scanimage -d epkowa -T
As long as the installation is not secured, the driver should be specified as well.
When opening iscan-data with engrampa I´ve found the file
/usr/doc/iscan-data-1.36.0/SUPPORTED-DEVICES which contains
Epson Perfection V39 (requires iscan-plugin-gt-s650)

Nothing, because senseless!

The Perfection V39 is supported by the IScan packets.
From usr/doc/iscan-data-1.36.0/NEWS:

Code: Select all

----------------------------------------------------------------------
iscan-data-1.35.0                                         (2015-01-29)
----------------------------------------------------------------------
 * adds support for the following devices:
   - Epson Perfection V19 (requires iscan-plugin-gt-s650)
   - Epson Perfection V39 (requires iscan-plugin-gt-s650)
From usr/doc/iscan-data-1.36.0/SUPPORTED-DEVICES:

Code: Select all

Epson Perfection V39 (requires iscan-plugin-gt-s650)
The Perfection V39 is listed with the following data at http://www.sane-project.org/sane-mfgs.html#Z-EPSON:

Code: Select all

Model: Perfection V39
Interface: USB
USB id: 0x04b8/0x013d
Status: Unsupported
Comment: supported by the epkowa backend plus non-free interpreter
Backend: epson2 (1.0.124 (unmaintained))
Manpage: sane-epson2
The model GT-S650 is listed as follows:

Code: Select all

Model: GT-S650
Interface: USB
USB id: 0x04b8/0x013d
Status: Unsupported
Comment: supported by the epkowa backend plus non-free interpreter
Backend: epson2 (1.0.124 (unmaintained))
Manpage: sane-epson2
The USB ID is the same for both scanners and therefore the scanner functionality is the same. Difference will probably be in the included software and in appearance. I would stay with the epkowa backend.
The only plugin I´ve found is iscan-plugin-gt-s650-1.1.0-2.x86_64.rpm
Where? Another RPM package that does not work without additional work. Probably very old.

Hello mimosa and galmel
Currently I've no time left for the scanner. If I've to scan some document I'll do it with MX (thanks to grub for the multiboot) then return to Salix.
I'll return to configure this scanner as soon as I can with all your advice.
Many thanks again
