I want to build a derivation that makes udev changes. Is there something additional I need to consider in such a case? Does it involve:
https://github.com/NixOS/nixpkgs/blob/0bfd0187dafe3f597355e6be16b7b9a5f4b90376/nixos/modules/services/hardware/udev.nix
somehow?
(BTW, the package in question is midisport-firmware.)

I had a look and the consensus seems to be to add udev rules to $out/lib/udev/rules.d/ and then add the package to services.udev.packages = [ my-package ]; either directly in configuration.nix or through a module. Below is a couple of example packages that do this.
NixOS:master ā dje4321:brightnessctl
opened 02:42PM - 16 Jun 18 UTC
###### Motivation for this change
Adding brightnessctl for better backlight supā¦ port. brightnessctl package is what provides the binary and the brightnessctl module enables the udev rule for access from userspace for anyone in the video group.
###### Things done
- [ ] Tested using sandboxing ([nix.useSandbox](http://nixos.org/nixos/manual/options.html#opt-nix.useSandbox) on NixOS, or option `sandbox` in [`nix.conf`](http://nixos.org/nix/manual/#sec-conf-file) on non-NixOS)
- Built on platform(s)
- [X] NixOS
- [ ] macOS
- [ ] other Linux distributions
- [ ] Tested via one or more NixOS test(s) if existing and applicable for the change (look inside [nixos/tests](https://github.com/NixOS/nixpkgs/blob/master/nixos/tests))
- [X] Tested execution of all binary files (usually in `./result/bin/`)
- [ ] Tested compilation of all pkgs that depend on this change using `nix-shell -p nox --run "nox-review wip"`
- [ ] Fits [CONTRIBUTING.md](https://github.com/NixOS/nixpkgs/blob/master/.github/CONTRIBUTING.md).

## Usage
# In NixOS, simply add this package to services.udev.packages:
# services.udev.packages = [ pkgs.android-udev-rules ];
stdenv.mkDerivation rec {
pname = "android-udev-rules";
version = "20191103";
src = fetchFromGitHub {

Thanks very much!
Let me chew on that a bit and try it. Iāll report my results back here.
OK, I havenāt had a chance to try this yet because thereās also a firmware component that must be built. The package depends up fxload, which is available. I just need to get a better understanding about how that works in a NixOS context.
Was there ever a solution to this? Iād like to use my m-audio uno interface under nixos.
ah. I donāt really understand how to apply that to making midisport-firmware available in nixos. I was hoping for a nixos setting perhaps. Iāll have to circle back to this when I have time to delve into what udev is and so forth.
You are probably better off opening a new thread than necrobumping a solved one, then.
