The recommended method of getting joystick events on Windows, for devices that do not fall under the XInput API, is to use the raw input API (WM_INPUT). I saw that winit already does this for mouse & keyboard events, but not yet for joysticks.

Since I've got a need for this in my own project, I hope to soon give a shot at implementing this on Windows, but if anyone else who is more familiar with this API can implement it faster than I could, that would be appreciated.
