| Enable the built-in USB serial interface present in some Espressif |
| MCUs like the ESP32-C3. |
| |
| 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. |
