摘要：
A peripheral device, with first and second communication conductors, is connectable to a computer having one of a first interface and a second interface. The first interface communicates with the peripheral device over a differential data connection having a first data conductor and a second data conductor. The second interface communicates with the peripheral device over a clock conductor and a single ended data connection which includes a data conductor. The peripheral device includes an interface detection component coupled to the first and second communication conductors to detect which of the first and second interfaces the peripheral device is connected to.
