Looks like your device is more defective than your english :-/

Anyway, the issue with iscan-data's post-install script is device
independent so that remains to be fixed.  In the mean time though, I've
noticed that iscan-data also includes a /lib/udev/hwdb.d/iscan-data.hwdb
that has an entry for the Perfection V10.

Based on what I see on a Devuan beowulf setup (basically Debian buster
w/o systemd), that ought to be enough to make the device usable for a
logged in user.

Hope this helps,
