By default, OnlyKey device (https://crp.to/p/) won't work on Linux (and, therefore, NixOS). This is unintuitive and requires one to search for a solution in the documentation. This change allows one to enable OnlyKey device support directly from their NixOS configuration.
*** NixOS *** NixOS is a Linux distribution based on the purely functional package management system Nix. More information can be found at http://nixos.org/nixos and in the manual in doc/manual.
