TinyUSB examples includes external repos aka submodules to provide low-level MCU peripheral's driver to compile with. Therefore we will firstly fetch those mcu driver repo by running this command in the top folder repo
```
$ git submodule update --init --rescursive
$ git submodule update --init --recursive
```
It will takes a bit of time due to the number of supported MCUs, luckily we only need to do this once.

Theory of operation:
The NUC121/NUC125/NUC126 USBD peripheral has eight "EP"s, but each is simplex,
so two collectively (peripheral nomenclature of "EP0" and "EP1") are needed to
implement USB EP0. PERIPH_EP0 and PERIPH_EP1 are used by this driver for
EP0_IN and EP0_OUT respectively. This leaves up to six for user usage.
