Calling owners of Logitech keyboards and USB speakers with LCDs

In case anyone has an old Logitech keyboard or USB speaker with a built-in LCD, please give this PR a go: nixos/lcd: add support for Logitech LCD by peterhoeg · Pull Request #78166 · NixOS/nixpkgs · GitHub

I don’t have all the hardware that the project supports, so I have only tested with a Z10.
