    I have used RegisterLayout to setup identification for a home-grown HID following the Unity Manual https://docs.unity3d.com/Packages/c...483301.1603385957#overriding-the-hid-fallback

    ListLayouts shows the layouts as correctly registered on both the Editor & the Quest 2

    When run in the Unity Editor, the HID is correctly identified and the controls are listed correctly.
    When run on Oculus Quest 2, the HID is identified as AndroidJoystick and only standard AndroidJoystick controls are listed in InputDevice.allControls.
    Comparing the InputDevice.description.capabilities, the VendorID & ProductID are identical (which are the items the InputDeviceMatcher is based on) but MatchPercentage() gives a score of 0 on Quest compared to a score of 0.6 on Windows.
    It gives AndroidJoystick a MatchPercentage of 0.75 but I can't see how.

    Any ideas?

    Hi, do you mean you pass raw HID data on Oculus somehow directly to Input System? Or you mean you pass HID data to Android, then Android converts it to motion events, and then you want to get your custom device class?

    For second case, because android reports same data for motion events, we do a bit of custom classification here https://github.com/Unity-Technologi...m/Plugins/Android/AndroidSupport.cs#L107-L161 this probably needs to be extended to inject more data. But our AndroidGamepad should be fairly universal, currently supporting 48 axes and 220 buttons, do you need more or you need other type of data?
