A universal controller supports multiple different computer protocols to enable endpoint communications between two or more electronic devices according to a desired protocol. Controller firmware modules embedded in an integrated circuit identify a particular protocol in a data communication received from a first external device, select from among multiple protocol drivers embedded in the modules a protocol driver corresponding to the particular protocol identified, and transmit content of the received data to one or more second external devices according to the particular protocol. The universal controller includes a bus translator module parsing bit streams received from the first external device into protocol data, status data, and content data, a protocol firmware module providing multiple different protocols drivers, and a control interface selecting, responsive to protocol data parsed, a particular protocol driver to establish data communication with a second external device according to the desired communication protocol. Data communication may originate from any of multiple second external devices, and different protocols may be transmitted simultaneously for multi-channel or redundant communication between the external devices.
