* <b>USE_INTERNAL_SERIAL</b> - ( \ref Group_Descriptors ) \n
* Some AVR models contain a unique 20-digit serial number which can be used as the device serial number, while in device mode. This
* allows the host to uniquely identify the device regardless of if it is moved between USB ports on the same computer, allowing
* allocated resources (such as drivers, COM Port number allocations) to be preserved. To make the library use this value for the
* device's serial number, define this token in the project makefile, set it to a unique string descriptor index (i.e. one not used
* elsewhere in the device for a string descriptor) and set the Device Descriptor's serial number descriptor index entry to the
* USE_INTERNAL_SERIAL value.

* <b>FIXED_CONTROL_ENDPOINT_SIZE</b> - ( \ref Group_EndpointManagement ) \n
* By default, the library determines the size of the control endpoint (when in device mode) by reading the device descriptor.
