First, scan through these helpful links:

• https://www.reddit.com/r/linux_gaming/comments/nypsi1/updated_guide_to_remapping_keys_on_linux_using/
• https://github.com/systemd/systemd/blob/main/hwdb.d/60-evdev.hwdb
• https://search.nixos.org/options?channel=23.11&show=services.udev.extraHwdb&from=0&size=50&sort=relevance&type=packages&query=hwdb

This is what I ended up adding to /etc/nixos/configure.nx file. This is specific to the keyboard that is in my laptop. Unless you also have the same basic US keyboard they shiped with my framework 13 (circa April 2024), you will want to modify this udev rule accordingly. The information on how to do that can be found in the reddit post and 60-evdev.hwdb file

To successfully pair multiple PS4 Move Controllers on Windows with the psmove utility:

1. Make sure your computer supports bluetooth, and that bluetooth is currently activated.
2. Download one of the release Windows binary distributions from https://thp.io/2010/psmove/. I picked the MSVC Win64 build of 4.0.12, which seems to work mostly ok.
3. Extract the archive. Copy the contents of the "lib" folder into the "bin" folder.
4. Open an administrator cmd shell, and cd to the bin folder. Leave this shell open for the following commands.
5. Plug exactly one move controller into a working USB port, and turn the controller on.
6. Run psmove.exe pair, and follow the instructions it prints. You may will see an OS notification popup to confirm the device pairing, and you should hit approve. You may need to try this process multiple times. If this worked, then the commandline output will look something like this:

Connected controllers: 1
