Aim : To achieve simple request/response communication using ESP32C3's USB Serial/JTAG Controller.

Example: I will connect ESP32C3's USB Serial/JTAG Controller lines to PC's USB port then from PC I will send any message using Serial Terminal and then I need to receive it in code and perform Actions.

How can I receive/send data in code using espidf?

I would suggest you to use the USB CDC-ACM (Communication Device Class - Abstract Control Model) feature. The USB Serial/JTAG Controller allows serial communication directly through the USB port without the need for external USB-to-UART chips, and you can handle this in your ESP-IDF application using standard serial communication functions. I hope that will help.
