Use condition variable instead of active waiting for device event handling
With some devices and USB hardware the reconnect of a device might actually
be faster than the check interval of the active waiting loop. With mutexes
and a condition variable we will not miss the moment of reconnect anymore,
even if it is really quick (like 7ms, right DanyL?)
