In one embodiment, an apparatus includes a host controller to couple to an interconnect to which a plurality of devices may be coupled. The host controller may include: a first driver to drive first information onto a first line of the interconnect; a second driver to drive a clock signal onto a second line of the interconnect; and a mode control circuit to cause the second driver to drive the clock signal onto the second line of the interconnect in a first mode and to cause the first driver and the second driver to drive differential information onto the first line and the second line of the interconnect in a second mode. Other embodiments are described and claimed.

A method to enable a vehicle's embedded USB Host system to connect to multiple mobile devices through a USB Hub, regardless of whether the mobile devices are configured to act as USB Hosts or USB Devices, without USB On the Go (OTG) controllers or additional vehicle wiring or inhibiting the functionality of any consumer devices connected to the same USB Hub. Preferably, the method is configured to provide that no additional cabling or hardware changes to accommodate this capability. The method can be employed between a vehicle's embedded USB Host, USB Hub and at least one consumer accessible USB port. When the consumer device is acting as a USB Host, signals between the consumer device and the vehicle's embedded USB Host are processed through a USB bridge, thereby rendering the consumer device compatible with the vehicle's embedded USB Host.

In some embodiments, a system is provided for communicating USB information via an extension medium. The system comprises an upstream facing port device (UFP device) and a downstream facing port device (DFP device). The UFP device and the DFP device are communicatively coupled via a non-USB extension medium, and allow a host device communicatively coupled to the UFP device and a USB device communicatively coupled to the DFP device to communicate via USB-compliant techniques. In some embodiments, the DFP device generates synthetic request packets to request additional data packets from the USB device compared to those requested by the host device. In some embodiments, the DFP device is configured to store a request packet in a packet queue if the request packet is received from the UFP device while the DFP device is busy receiving a response to a previous synthetic request packet from the USB device.

A cross-network bridging apparatus includes a bus interface and bridging circuitry. The bus interface is configured for connecting to a system bus. The bridging circuitry is configured to translate between (i) system-bus transactions that are exchanged between one or more local devices that are coupled to the system bus and served by the system bus and one or more remote processors located across a network from the apparatus, and (ii) data units that convey the system-bus transactions, for transmitting and receiving as network packets over the network to and from the remote processors.

A method of automatic identification of PCIe configuration of a server and preventing operation if each slimline connector connected with a PCIe device is found connected to an incorrect slot of a mother board utilizes a combination of first and second signals of two null interfaces of the first connector as that ID signal and a combination of third and fourth signals of the two interfaces of a second connector as that ID signal. The CPLD receiving the ID signals detects whether the first and second slimline connectors are in their specified and correct slots. Powering on of computer is not permitted if incorrect connection is found, and a warning prompt is generated. A PCIe channel width for each slimline is automatically configured if no incorrect connection is found. A server applying the method is also disclosed.

A communication interface adapter is provided to include a first communication interface to be electrically connected to a computer device, a second communication interface to be electrically connected to the peripheral device, a microcontroller, a communication interface hub electrically connected to the first communication interface and the microcontroller, and a switch unit electrically connected between the communication interface hub and the second communication interface. The switch unit is controlled by the microcontroller to make or break connection between the communication interface hub and the second communication interface.

The present disclosure provides devices, methods, and systems for controlling a connection, via a communication apparatus, between a first apparatus and a second apparatus. For instance, the methods may include generating a connection signal in response to determining that a second apparatus has established a new connection with the communication apparatus; generating a control signal based on the connection signal; and changing, based on the control signal, a connection state between the first apparatus and the communication apparatus to cause a new connection relationship between the first apparatus and the second apparatus to be established for a communication between the first apparatus and the second apparatus.

In an example in accordance with the present disclosure, a compute device is described. The compute device includes a host controller to 1) receive identification data of peripheral devices coupled to a computing dock and 2) compare the identification data with values stored in a database. A stored value indicates a combination of peripheral devices previously coupled to the computing dock. The compute device also includes a device connection controller to, responsive to the identification data matching a stored value, retrieve operational data for the peripheral devices from the database. The device connection controller is also to connect the compute device with the peripheral devices based on operational data retrieved from the database.

In some embodiments, a system for communicating USB information via an extension medium is provided. The system comprises an upstream facing port device (UFP device) and a downstream facing port device (DFP device). The UFP device is communicatively coupled to a host device via a USB-compliant connection. The DFP device is communicatively coupled to at least one USB device via a USB-compliant connection and communicatively coupled to the UFP device via a non-USB extension medium. The DFP device is configured to receive, from the UFP device, an incoming request packet addressed to a first USB endpoint provided by a USB device; and hold transmission of an outgoing request packet based on the incoming request packet to the USB device in response to determining that a ping response packet has not yet been received from the first USB endpoint.
