//! The USB device interrupt handler.
//!
//! This the main USB interrupt handler entry point for use in USB device
//! applications.  This top-level handler will branch the interrupt off to the
//! appropriate application or stack handlers depending on the current status
//! of the USB controller.
//!
//! Applications which operate purely as USB devices (rather than dual mode
//! applications which can operate in either device or host mode at different
//! times) must ensure that a pointer to this function is installed in the
//! interrupt vector table entry for the USB0 interrupt.  For dual mode
//! operation, the vector should be set to point to \e USB0DualModeIntHandler()
//! instead.
//!
//! \return None.
