Abstract
Circuits, methods, and apparatus that may compensate for an incompatibility between connection detection schemes used by different interface circuits for different connector receptacles. One example may provide an active pull-down that normally provides a pull-down resistor and provides an open circuit for a period of time following a disconnection of an interface from a cable.
