Is HID PID fully implemented on Windows / Linux (i.e. does it load a generic driver like USB ACM or USB HID mouse / keyboard). I remember that I looked into this, but couldn't find any recent devices that use this.
In order to get my wheel working on linux, I had to modify the arduino library to comply with the spec. It was clearly written to work with windows. I haven't tried it on windows yet, but I suspect that it wouldn't work. There are smaller wheel vendors with stale customer support tickets regarding linux incompatibility.
I assume this is one of the reasons that larger companies like Logitech provide their own custom drivers, despite being 90% compatible with the generic HID spec.
If you're curious, I forked the arduino library with my fixes: https://github.com/sgtnoodle/ArduinoJoystickWithFFBLibrary
I'm loosely involved with the HapticsIF (https://hapticsif.org). They are working towards a new haptic usage page. If I remember the sentiment of those meetings correctly, USB PID was considered very old and not easy to work with. Besides that a more recent haptics Usage page was considered limiting (only for single effects).
I got Dirt Rally sorta working too, but it wasn't really playable because the game doesn't seem to support multiple input devices, and I wired up my pedals through a separate 32u4 MCU.
