Hi Kelly, and thanks, with a couple questions on specific points: On Mon, Oct 17, 2022 11:39:14 AM -0400, Kelly Price wrote: > I can answer that from a user's perspective.

but does the hub **NEED** to be powered? Until now, I've done with a four port "passive" hub attached to my NUC desktop, for: mouse, keyboard, webcam & printer/scanner. Replacing that with a powered hub would (besides being ~25/30 EUR more, AFAICT) be a problem because I already am out of easy to reach electrical sockets... > And it's best if you use the "sane-releases" PPA, because Ubuntu can > lag behind. It should work out of the box with the PPA. on the software side... what I need is the most is a command line utility to scan at maximum resolution from inside a shell script. That would be still "scanimage", or something else here? This said, I have discovered that there are also packages by Canon itself: https://www.canon-europe.com/support/consumer_products/products/scanners/lide_series/canoscan-lide-400.html?type=drivers&language=en&os=linux%20(64-bit) but since they are declared for Ubuntu 18.04 LTS, the PPAs you mention should be much better for 22.04, right? I mean, these: https://launchpad.net/~sane-project/+archive/ubuntu/sane-release Thanks, looking forward to these confirmation so I can go to the store and buy this thing... Marco
