+/** \file
+ *  \brief USB controller events manager.
+ *
+ *  This file contains macros and functions relating to the management of library events, which are small
+ *  pieces of code similar to ISRs which are run when a given condition is met. Each event can be fired from
+ *  multiple places in the user or library code, which may or may not be inside an ISR, thus each handler
+ *  should be written to be as small and fast as possible to prevent possible problems.
+ *
+ *  Events can be hooked by the user application by declaring a handler function with the same name and parameters
+ *  listed here. If an event with no user-associated handler is fired within the library, it by default maps to an
+ *  internal empty stub function.
+ *
+ *  Each event must only have one associated event handler, but can be raised by multiple sources by calling the
+ *  event handler function (with any required event parameters).
+ *
+ *  \note This file should not be included directly. It is automatically included as needed by the USB driver
+ *        dispatch header located in LUFA/Drivers/USB/USB.h.
