The funcard USB software is especially developed for all who regularly use a standard/slow funcard 6 for eg updating a CAM. Programming a standard funcard 6 to update a CAM takes minutes. The fun USB is the solution for time consuming updating of a cam and a good alternative for the CAS interface. When the funcard USB has been programmed it acts like a "standard" funcard 6. All USB communication takes place in the funcard USB.
