Gamepad not working on MacOS

[jasongerard]

I have a Microsoft X-Box One Elite 2 pad plugged in via USB. That is the name reported in Linux with an SDL ID of 030000005e040000000b000015050000

When I try on MacOS I get the same SDL ID but a name of Controller.

I'm running go run github.com/hajimehoshi/ebiten/v2/examples/gamepad@latest to test this.

On Linux the example renders and shows all the input. On Mac I just get the ID and name displayed so it seems ebiten. IsStandardGamepadLayoutAvailable() returns false for this id.

What's really baffling to me is that neither that SDL ID nor that name string (or anything with "X-Box", though "Xbox" is present) appear in any version of gamecontrollerdb.txt included with ebiten.

So my questions are:
How is this even working on Linux?

How should I debug this on Mac?
