// Initialization. The goal here is to call usbs_upd985xx_init()
// early on during system startup, to take care of things like
// registering interrupt handlers etc. which are best done
// during system init.
//
// If the endpoint 0 devtab entry is available then its init()
// function can be used to take care of this. However the devtab
// entries are optional so an alternative mechanism must be
// provided. Unfortunately although it is possible to give
// a C function the constructor attribute, it cannot be given
// an initpri attribute. Instead it is necessary to define a
// dummy C++ class.
