Ongoing problems connecting a Canon CanoScan 4400F scanner to Linux Mint

Linux Mint 19 “Tara” could recognize my Canon CanoScan 4400F scanner but couldn’t properly communicate with it, attempts at fixing the problem led to a complete messing up of the OS, and Linux Mint 20 “Ulyana” can no longer recognize it at all.
