20100165528 | UPSTREAM DEVICE OVERVOLTAGE DETECTION WITH DEACTIVATION OF DOWNSTREAM DEVICE POWER - For one disclosed embodiment, a controller comprises communication circuitry to communicate over one or more data lines with a downstream device external to an upstream device having the controller and detection circuitry to detect on at least one of the one or more data lines a voltage having a value in excess of a reference value. The detection circuitry is to deactivate a supply of power over one or more power lines to the downstream device in response to detection on at least one of the one or more data lines of a voltage having a value in excess of the reference value. Other embodiments are also disclosed. | 07-01-2010 |

20140149609 | DETECTING DEVICE DISCONNECT IN A REPEATER - A method for detecting device disconnect in a repeater is disclosed herein. The method includes receiving a disconnect indication comprising a voltage swing occurring on a data channel for a peripheral device. The method also includes receiving a start-of-frame indication that indicates that a threshold consecutive number of bits of the same data value has been received. The method further includes sending a device disconnect message to a host based on the disconnect indication and the start-of-frame indication. | 05-29-2014 |

20140173166 | REDUCTION OF IDLE POWER IN A COMMUNICATION PORT - 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. | 06-19-2014 |
