@vwasteels Have you already tested without the dongle?

Unfortunately, there is a plethora of possible hardware and the team can't have them all or even test them all, so while Recalbox has MANY compatible joysticks, not all of them work.
Probably your problem is a driver incompatibility that only a developer could solve, but for that it is necessary that a developer has a joystick like this and compatible hardware, which unfortunately I think is unlikely.

We depend on user feedback to ensure compatibility, but your joystick is not listed as compatible:

And your dongle doesn't either:

Unfortunately, I don't think there is a solution in this case.

You can try resetting to factory defaults, option available through the advanced settings menu, you will not lose any personal files, but you will lose all custom settings. But it's just a possibility to be tested, I can't guarantee it will solve it.
