FTDI provides official, certified drivers that ensure stability and security. It is highly recommended to download drivers directly from the official repository rather than third-party websites. Virtual COM Port (VCP) Drivers
On Windows, expand . You should see an entry labeled USB Serial Port (COMx) , where 'x' is the assigned port number. Always download drivers directly from the official FTDI
Change your USB cable. Many cheap USB cables are designed solely for charging mobile devices and lack the internal data lines needed for UART communication.
When you plug an FT231X device into a computer, the operating system detects its Vendor ID (VID 0403 ) and Product ID (PID 6015 ). The driver acts as the translator, mapping these hardware IDs to software-accessible communication channels. It is highly recommended to download drivers directly

Look for , where "x" represents the assigned port number (e.g., COM3).
If your software (like Arduino IDE or a Python script) cannot read/write to the port, add your user account to the dialout group: sudo usermod -a -G dialout $USER Use code with caution. Log out and log back in for changes to take effect. Verifying Successful Installation
These drivers cause the USB device to appear as an additional COM port available to the operating system. Application software can access the device exactly as it would a standard physical COM port.
