Abstract:
A peripheral device connectable to a computer, the 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 at least a first data conductor, and a clock conductor, the peripheral device comprising:first and second conductors configured for connection to the first and second data conductors when the computer includes the first interface, and configured for connection to the first data conductor and the clock conductor when the computer includes the second interface; an interface detector, operably coupled to at least one of the first and second conductors, configured to detect which of the first and second interfaces the peripheral device is connected to, based on sensed signal levels on at least one of the first and second conductors, and to provide a connection output indicative of the detected interface; and a controller component, operably coupled to the interface detection component, configured to communicate with the computer over the first and second conductors according to a protocol corresponding to the detected interface.
