Abstract
An interface for detecting connected peripheral devices. The interface comprises a jack and a control unit determining the power requirements of peripheral devices, the control unit detecting the potential of two specified nodes upon connection of the device. If power is required, the control unit supplies the power and performs related commands according to device identification received from the connection. If no power is required, the control unit measures a resistor-capacitor (RC) equivalent value inside the peripheral device, and compares the measured RC values with RC values in a database.
