 ### Cores with built-in support
 
-Following core has Tinyusb as either the primary usb stack or selectable via menu `Tools->USB Stack`. You only need to include `<Adafruit_TinyUSB.h>` in your sketch to use.

+  ESP32 port relies on Espressif's [esp32-hal-tinyusb.c](https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/esp32-hal-tinyusb.c) for building usb descriptors which requires all descriptors must be specified in usb objects declaration i.e constructors. Therefore all descriptor-related fields must be part of object declaration and descriptor-related API have no effect afterwards for this port.
