Generic HID device not showing inputs

[yani992]

Hi, I am trying to use the Joystick Mapping functionality of your VERY USEFUL tool. I have many input devices (joysticks, throttle, joypad, button box, etc.) and they all show in the list. But when I try to select my custom HID device (built on a Teensy and perfectly working in Windows/MSFS/DCS) it does not show any available input in the list, so I cannot map them in the xml config file. The device has more than 32 buttons (around 80), might it be the problem?

Any hint is appreciated. Thanks.
