Corsair

CORSAIR is an American computer peripherals and gaming brand.

Its possible to configure its keyboards and mice with an open source driver: ckb-next

Example config for ckb-next

# /etc/nixos/configuration.nix
{ config, pkgs, ... }:

{
  # ...
  hardware.ckb-next.enable = true;
}

Seehardware.ckb-nextfor more configuration options.

Limitations

Doing the above will enable the background service and install ckb-next. Yet (as of writing) you still have to manually run/open ckb-next on launch before it works.

If you find a way to automate this, please append to the wiki!

Not a great way of doing it, but it works for me. Create ~/.config/autostart/ckb-next.desktop, open it in your favorite text editor and type:

[Desktop Entry]
Categories=Settings;System;
Comment[en_US]=Corsair keyboard driver user interface
Comment=Corsair keyboard driver user interface
Exec=<Location of ckb-next executable> -b
GenericName[en_US]=
GenericName=
Icon=ckb-next
Keywords=ckb;corsair;keyboard;rgb;
MimeType=
Name[en_US]=ckb-next
Name=ckb-next
Path=
StartupNotify=true
Terminal=false
TerminalOptions=
TryExec=<Location of ckb-next executable>
Type=Application
Version=1.0
X-KDE-SubstituteUID=false
X-KDE-Username=

The -b makes it run in the background

I was also running into this issue when I was running it manually; by using the .desktop file, I no longer have this issue. Lastly, every time you get a new version of ckb-next, you'll need to update the path in TryExec and Exec (both are the same).

A simple way to find the location of ckb-next is to search for it in the Kickoff Application Launcher (or equivalent, not KRunner) > Right Click > Edit Application then copy what is in the "Program" field. That way, if you haven't run a clean in a while and have an older version of ckb-next still installed, you're grabbing the right one.
