There is: arduino uno with two joysticks (native Arduin), which sends usb / serial data to my computer with linux, a program that reads data. This program should emulate a joystick. The data is successfully read, but how to emulate a joystick is not clear.

What are the linux libraries / utilities for this purpose?

Why use USB / serial ? Why not take https://github.com/MHeironimus/ArduinoJoystickLibrary and turn your Arduino into a full USB HID device? In this case, you will not need any additional programs on your linux PC.

If you still want to do perversions emulation - the easiest way to do this with libsuinput
