+ *  <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

  *  <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
