- * \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).
