Arduino Port Not Found USB Serial CH340 Driver

Arduino Port Not Found Or Not Detected. NodeMCU Too.

Fix Arduino Port Not Found USB Serial CH340 Driver – Are you just started using Arduino Uno and when you want to upload a program, the Arduino port is not found? Why is the Arduino Uno port not detected by the Arduino IDE?

In the market there are types of Arduino. Most Arduino with made in China use the CH340 chip as a USB Bus Converter.

Likewise ESP8266 NodeMCU V3, which uses the ESP8266 chip as its microcontroller, some models also use USB Serial CH340.
