Abstract: A circuit including a first pin connection, a second pin connection, a first diode-switch arrangement and a second diode-switch arrangement. The first diode-switch arrangement is connected in series and configured to allow a current to pass from the second pin connection to the first pin connection. The second diode-switch arrangement is connected in series and configured to allow a current to pass from the first pin connection to the second pin connection. An energized state of the first and second diode-switch arrangements is determined according to a voltage detected on the first or second pin connection.

Abstract: An apparatus and method for coupling a host computer to one or more peripherals or for coupling peripherals to one another. In one example, the apparatus includes a hub having an upstream port for coupling with the host computer and one or more downstream ports for coupling with the one or more peripherals; and a local host dynamically coupled with the upstream port. In one example, when the host computer is not coupled with the upstream port, the local host communicates with the peripherals; and when the host computer is coupled with the upstream port, the local host disconnects from the upstream port so that the host computer communicates with the peripherals through the hub. In this manner, the apparatus may be used to couple peripherals to a host computer, or when a host computer is not present, the data from the peripherals may be communicated through the local host. Other embodiments are also disclosed.

Abstract: A wireless peripheral controller connects multiple wireless game controllers to a game console across a communication port. A connector simulates the appearance of connecting a device to another communication port. Upon detecting the connection event, the game console queries the communication port associated with the connection event. A bus reset detector alerts the wireless peripheral controller. The alerted wireless peripheral controller signals the game console through the original communication port with the appropriate configuration instructions to obtain a unique device address for an additional wireless game controller. Using the unique device addresses, the wireless peripheral controller receives and responds to traffic intended for other communication ports through the original communication port.
