Abstract:
A peripheral device connectable to a computer having one of a first interface and a second interface, the first interface communicating with the peripheral device over a differential data connection including a first data conductor and a second data conductor, and the second interface communicating with the peripheral device over a single ended data connection, including a first data conductor, and a clock conductor, the peripheral device comprising:first and second communication conductors configured for connection to the first and second data conductors in the differential data connection when the computer includes the first interface, and configured for connection to the first data conductor in the single ended data connection and the clock conductor when the computer includes the second interface; a connection element connecting a predetermined one of the first and second communication conductors to a voltage potential; an interface detection component, coupled to the first and second communication conductors, configured to detect which of the first and second interfaces the peripheral device is connected to and to provide a connection output indicative of the detected interface; and a controller component, coupled to the interface detection component, configured to communicate between the peripheral device and the computer over the first and second communication conductors according to a protocol corresponding to the detected interface based on the connection output.
