static int	LibUsb.handleEventsCompleted(Context context, IntBuffer completed) Handle any pending events in blocking mode.
static int	LibUsb.handleEventsLocked(Context context, long timeout) Handle any pending events by polling file descriptors, without checking if any other threads are already doing so.
static int	LibUsb.handleEventsTimeout(Context context, long timeout) Handle any pending events.
static int	LibUsb.handleEventsTimeoutCompleted(Context context, long timeout, IntBuffer completed) Handle any pending events.
static void	LibUsb.hotplugDeregisterCallback(Context context, HotplugCallbackHandle callbackHandle) Deregisters a hotplug callback.
