+ * <b>NO_SOF_EVENTS</b> - ( \ref Group_Events ) \n
+ * By default, there exists a LUFA application event for the start of each USB frame while the USB bus is not suspended in either host or device mode.
+ * This event can be selectively enabled or disabled by calling the appropriate device or host mode function. When this compile time token is defined,
+ * the ability to receive USB Start of Frame events via the \ref EVENT_USB_Device_StartOfFrame() or \ref EVENT_USB_Host_StartOfFrame() events is removed,
+ * reducing the compiled program's binary size.
