[sane-devel] perfection v10

[valerio]

hi to everyone,
I have had a problem with the scanner in object for several days.
I installed iscan (iscan-gt-s600-bundle-2.30.4.x64.deb), launching from 
the folder in brackets "./install.sh --without-network"

I've done it several times, along with sane, following different guides, 
but it doesn't work ...
he tells me he can't send commands to the scanner (I go to memory)

during installation it tells me:

Extracting iscan-plugin-gt-s600 (2.1.3-1) ...
Configuration of iscan-data (1.39.1-2) ...
expr: syntax error: missing argument after "-"
tail: invalid number of lines: "/lib/udev/rules.d/60-libsane.rules"
Iscan configuration (2.30.4-2) ...
Configuration of iscan-plugin-gt-s600 (2.1.3-1) ...
Processing triggers for man-db (2.9.0-2) ...
Processing triggers for mime-support (3.64) ...
Processing triggers for desktop-file-utils (0.24-1) ...
Processing triggers for udev (244-3) ...

I did various tests, I configured epkowa.conf, I checked the rules on 
/etc/udev/rules.d (now there are no rules at the last test ...).

sometimes it starts iscan, but it cannot give commands to the scanner, 
sometimes it gives me error messages without even opening iscan ...

I do not know what to do..

does anyone have any help, or any suggestions?

thank you
valerio
