Discovery of connections utilizing a control bus. An embodiment of a method includes detecting a transition of a control bus from a high state to a low state by a source device, the source device being configured to be coupled with a sink device via an interface, the interface including the control bus, the source device including a pullup device and the sink device including a pulldown device;pulsing the control bus to a high state at the source device; and upon detecting by the source device that the control bus remains in the high state ceasing the pulsing of the control bus to the high state, and transitioning the source device from a disconnected state to a connected state.
