Right now I have a passive 4 ports hub for mouse, keyboard, webcam and
printer/scanner.  A powered hub would be a problem, regardless of its
cost, because of course it needs a socket..

I could attach a new active hub to the already installed passive one,
but my custom desk has no more easy to reach sockets. I CAN find a
solution, of course, but I'll go for an active hub only if told that
it is absolutely needed for this scanner. Is it?

that package is for Ubuntu 18.04. After posting here, I also asked on
the sane-devel, and just a few minutes ago they pointed me to the sane-project PPAs:
https://launchpad.net/~sane-project/+archive/ubuntu/sane-release

(for the record, what I really need is to drive the scanner at maximum
resolution within a bash script, not a fancy GUI)

Further comments/help still welcome, of course.

Thanks,
