Zusammenfassung:	Exemplary embodiments are directed to broadcasting data on a USB system. The system includes a USB host and multiple broadcast-capable USB devices. Each USB device includes at least a default control endpoint for receiving control information and an isochronous sink endpoint for receiving a broadcast stream. The USB host programs a shared device address to an address register of each USB device such that all broadcast-capable USB devices programmed to that shared device address will accept the broadcast stream. One of the USB devices at the shared device address is set as a primary broadcast slave that will respond to non-isochronous transfers to the shared device address. All other USB devices with the shared device address are set to secondary slaves that ignore non-isochronous transfers to the shared device address.
