Abstract: A connection controller for a serial bus network includes physical layer processing circuitry for performing the protocol of the physical layer of the network to establish communications with first, second and third nodes. The first node is specified as an initiator node and the second node is a target node of the first node. The physical layer processing circuitry is energized by power supplied from the first node. To reliably establish connections between desired nodes in a first-to-win racing environment, a delay time is introduced in response to the physical layer processing circuitry being energized. During the delay time, a logical connection is established between the first and second nodes and the third node is set in a disabled state.
