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