Abstract:
Techniques for reducing idle power consumption of a port are described herein. An example method includes determining device presence using a pull-down resistor disposed in a downstream port. The method also includes initiating a low power state of a link between the downstream port and an upstream device. The method also includes disabling the pull-down resistor in response to initiating the low power state.
