The LILYGO TTGO T8 ESP32-S2 has a USB-to-UART bridge on board. The USB D-/D+
signals of the USB-C connector are connected via DIP switches either to this
USB-to-UART bridge (default) or to GPIO19/GPIO20 of the ESP32-S2. To use the
USB-OTG interface of the ESP32-S2, the USB D-/D+ signals must be connected to
USB OTG interface of the ESP32-S2, the USB D-/D+ signals must be connected to
GPIO19 and GPIO20, see section \ref esp32s2_lilygo_ttgo_t8_pinout "Pinout".
If the USB-to-UART bridge is used, module `stdio_cdc_acm` or module
`stdio_tinyusb_cdc_acm` can be enabled to use the USB interface also for the
console.
To use the USB OTG interface also for the console in this case, either the
`stdio_cdc_acm` or the `stdio_tinyusb_cdc_acm` module must be enabled.
This is automatically the case if the USBUS or tinyUSB stack is used.
The LILYGO TTGO T8 ESP32-S2 has a 32.768 kHz crystal on the board, which is
connected to GPIO15 and GPIO16 via DIP switches (default). The crystal can
