[sane-devel] UPDATE about: help to understand which of THESE scanner/printers is supported

[Kelly Price]

I would highly recommend a powered hub to guarantee full power to the
scanner, and a (surge-protected) power strip to get your PC's power in
reach.

The sane-release PPA has "scanimage" in its packages.  That hasn't
changed.  And yes, they're for 22.04.
