Methods and systems are disclosed for detecting a presence of a device that includes providing a clock driver having a pair of differential clock signal lines capable of connection to a device, providing a presence detection signal for transmission through the pair of differential clock signal lines, determining whether the presence detection signal is received through the pair of differential clock signal lines, and identifying the presence of the device if the presence detection signal is received through the pair of differential clock signal lines.
