	  Enable the built-in USB serial interface present in some Espressif
	  MCUs like ESP32-Cx.

	  This driver uses the peripheral called USB Serial/JTAG Controller
	  (USB_SERIAL_JTAG), which acts as a CDC-ACM interface towards the
	  USB host. The USB stack is built into the chip and accessed
	  by the firmware through a simplified API similar to a "normal"
	  UART peripheral.
