Abstract: A cable, adapter, or converter device is disclosed that enables a peripheral device (e.g., external display) normally connected only through a non-USB port to communicate with a host computer via a USB port in addition to its non-USB port. DDC-formatted signals from the peripheral device are converted to the appropriate format for input through the USB port, and signals transmitted to the peripheral device from the USB port are converted to the format recognizable by the external peripheral, allowing access to peripheral features via the host system.
