What are you planning to wire up (buttons, potentiometers, or Hall effect sensors)? What flight simulator is your primary target?
This typically means the MMJoy2 firmware hasn't been successfully uploaded. The Arduino Leonardo's default firmware is still present. Re-flash the .hex file, ensuring you selected the correct chip type and COM port.
Remember:

Downloading and installing MMJoy2 is a straightforward process. Here's a step-by-step guide:
: 3.3V/8MHz versions of these chips, as they can cause firmware instability. Status & Latest Versions mmjoy project - Новости и обновления
: Unlike writing custom Arduino sketches, MMJoy2 uses a visual Windows GUI to configure buttons and axes. What are you planning to wire up (buttons,
: The Arduino Pro Micro is highly recommended because of its small form factor and native USB HID support, which is essential for MMJoy2 to function correctly.
You’ll need an Arduino Pro Micro (ATmega32U4) or a Teensy 2.0 .
: The most reliable, virus-free place to download the latest updated packages is via community-maintained GitHub mirrors. Search for trusted repositories archiving megaMOZG13's work. The Arduino Leonardo's default firmware is still present
Recent versions of MMJoySetup.exe include built-in firmware upload capabilities. After launching MMJoySetup.exe, navigate to the "Firmware" tab, select your .hex file, and follow the prompts.
Navigate to the extracted folder and run MMJoySetup.exe .
Connect a potentiometer or TLE5011 sensor to the designated analog pins (VCC, GND, and Signal). In the MMJoy2 GUI, go to the tab.
The world of DIY flight and sim peripherals no longer requires expensive commercial boards like Leo Bodnar or BU0836A. With the provided in this guide (from the verified community repository), and a $3 STM32 Blue Pill, you can build a professional-grade USB controller with up to 128 buttons, 8 axes, rotaries, and LEDs.
