// 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.
