I think that means you need to patch SDL joystick with this boards control mapping, see:

https://hg.libsdl.org/SDL/file/bb68bb2d5ccb/src/joystick/SDL_gamecontrollerdb.h

pygame just gets the number of axes reported by SDL.

If you can't do it yourself you could also log a detailed bug, preferably with C code here:

https://bugzilla.libsdl.org/enter_bug.cgi

I also noticed later that SDL appears to map all 'joysticks' to emulate PS4/PS3/X-Box controllers so it may be that an 8 axis board will not work with SDL easily. Though again, they are the people to ask.

Let us know if you log a bug there and we can link it to this issue.

I think I'm not able to patch the SDL joystick and basically Pygame works good, the problem is only that pygame not see all axis that Windows see (8)... could you help me in some ways ?? thanks

We can't fix it in pygame, pygame in many instances is a wrapper around SDL which interfaces with the hardware like your particular board.

SDL has a predefined set of joysticks and if your board isn't on the list it won't pick it up. Plus, I believe SDL just shoves all joysticks/controllers into emulating one of the popular six axis controllers (Ps4/X-box) so it may not work easily.

My advice is to explain your problem to SDL on their issue tracker here. Explain that SDL doesn't pick up all eight axes of your board:

https://bugzilla.libsdl.org/enter_bug.cgi?product=SDL

And see what they say, you will also need to tell them the Vendor ID (VID) and Product ID (PID) of your board:

This issue is now open on the SDL bugzilla here:

The issue I opened with SDL was deemed to be a duplicate of this one:

https://github.com/libsdl-org/SDL/issues/3561

which remains unresolved.
