* <b>DEVICE_STATE_AS_GPIOR0</b> - ( \ref Group_Device ) \n
* One of the most frequenty used global variables in the stack is the USB_DeviceState global, which indicates the current state of
* the Device State Machine. To reduce the amount of code and time required to access and modify this global in an application, this token
* make be defined to fix the state variable into one of the three general purpose IO registers inside the AVR reserved for application

* <b>TOTAL_NUM_CONFIGURATIONS</b> - ( \ref Group_Device ) \n
* By default, the library determines the number of configurations a USB device supports by reading the device descriptor. This reduces
* the amount of configuration required to set up the library, and allows the value to change dynamically (if descriptors are stored in
