About

Some games/emulators seem to have troubles with the amount of provided additional information (pressure slider elements) that SDF and GPJ modes offer. Consider adding a new HID mode that provides a bare simple (and DirectInput-compatible) gamepad with just the common layout of an Xbox controller.

How

Thankfully most of the work has already been done by Microsoft and community members 😄 Adopt a slightly modified HID Report Descriptor as used by xusb22.sys which is well-known by games and "just works".

This is the one that should be used. It is the variant that splits the triggers into distinct axes/sliders instead of the weird backwards-compatibility choice they made with the combined axis. Maybe it's even worth experimenting with both variants in regards to compatibility.

Downside: since they don't use Report IDs it is not possible to tack on FFB to the same collection. And FFB doesn't help as long as e.g. RetroArch has no support for it anyway, so... Let's keep on tinkering 👀

I might have accidentally superseded this issue in this branch 😁
