* <b>NO_CLASS_DRIVER_AUTOFLUSH</b>
* Many of the device and host mode class drivers automatically flush any data waiting to be written to an interface, when the corresponding
* USB management task is executed. This is usually desirable to ensure that any queued data is sent as soon as possible once and new data is
* constructed in the main program loop. However, if flushing is to be controlled manually by the user application via the *_Flush() commands,
* the compile time token may be defined in the application's makefile to disable automatic flushing during calls to the class driver USB
* management tasks.
