-TinyUSB is completely thread-safe by pushing all ISR events into a central queue, then process it later in the non-ISR context. It also uses semphore/mutex to access shared resource such as CDC FIFO. Therefore the stack needs to use some of OS's basic APIs. Following OSes are already supported out of the box.

 The board support code is only used for self-contained examples and testing. It is not used when TinyUSB is part of a larger project. It is responsible for getting the MCU started and the USB peripheral clocked with minimal of on-board devices
