Fortnite gamepad

[rokzin84]

Hi.

Has anyone actually made a gamepad compatible with Fortnite with this library on a Seeedstudio XIAO SAMD21?
I have been trying for a month to make it recognize the joystick, but no joy :/

I can't for the life of me find out why it does not work, but I am a noob in this department.

Windows recognizes and lets me calibrate it, but in games or browser it does not work.
Is it the serial port that is the problem?
