In the world of embedded systems, robotics, and DIY electronics, few components are as ubiquitous as the USB-to-UART bridge. Among the most reliable and widely used chips in this category is the . This IC allows your computer to communicate with microcontrollers (like Arduino, ESP32, or STM32) via a simple USB connection, emulating a classic serial port.

Try a different USB port (preferably a USB 2.0 port instead of USB 3.0), swap the USB cable, or roll back to an older version of the FTDI driver (such as version 2.12.00). Issue 2: Driver Automatically Uninstalls or Overwrites When you plug in the device, it should

When you plug the device in, it will automatically register as /dev/ttyUSB0 (the number may change depending on how many USB serial devices are connected).

Drivers are generally for macOS 10.12 (Sierra) or later, as Apple includes a native driver ( AppleUSBFTDI ). You can lock the COM port number

The FT231X is a USB-to-UART (Universal Asynchronous Receiver-Transmitter) converter chip developed by FTDI (Future Technology Devices International). It's a popular IC used in many USB-UART adapter cables and modules, providing a simple and efficient way to connect devices with UART interfaces to a host computer via USB.

Switch from a USB 3.0 port to a USB 2.0 port. Avoid using unpowered USB hubs. Swap out the USB cable for one that explicitly supports high-speed data transfer. Issue 2: Yellow Exclamation Mark in Device Manager Cause: The driver is missing or corrupted.
