WinWing Hotas not properly recognized by DCS Steam Open Beta

[Patoruzu]

I bought an new WinWing Stick and although it is detected by DCS Steam, only the first 10 buttons are "available". Any idea on how to make it recognize the entire setup?

NOTE: the 10 buttons come probably from a regular gamepad. I tried controls to map the rest of buttons and axis, nothing worked.

Thanks in advance,
