A docking station and a control method thereof are provided. The docking station includes a first USB interface, a second USB interface, a video signal output terminal, a microcontroller, a first signal multiplexer, a second signal multiplexer, a video signal processor, and a video signal converter. The microcontroller determines whether the first USB interface or the second USB interface is connected to an electronic device. When the first USB interface is connected to the electronic device, the microcontroller sets the first USB interface as an uplink port. The uplink port receives a signal from the electronic device, and selects and outputs a video signal through the signal. The video signal processor is configured to receive and process the video signal. The video signal converter converts the video signal into a video output signal that is capable of being output to the video signal output terminal for playing.

In an example in accordance with the present disclosure, a system is described that includes a hub for routing data traffic between a first computing device and a second computing device. A detection device of the system detects a communication protocol between the computing devices. A switch of the system routes traffic directly between the computing devices when a first communication protocol is detected. When a second communication protocol is detected, the switch re-routes traffic of the first type from the first computing device back to the hub to convert the traffic of the first type to a second type and routes converted traffic directly to the second computing device.

A remote technical support system includes an edge device that operates as a highly secured conduit for a technician to view, access, and control a target device via a secure protocol over a connection medium between the edge device and the target device. The edge device's architecture allows it to selectively present numerous peripheral devices to the target device. The architectural components of the edge device can be controlled by a technician through a secure connection with a trusted server which allows authorized to access the edge device. The edge device also relays technician commands to and obtains diagnostic information from the target device and communicates feedback to the technician over the secure connection. The commands may be relayed to the target via the one or more selectively connected USB peripherals.

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.

A universal serial bus (USB) hub supporting multiple hosts and an automobile head unit using the same are provided. A USB hub circuit is set in the USB hub, which is coupled to external connectors through a bus matrix. Herein, an upstream port connector of the USB hub is coupled to the automobile head unit. When one device is coupled to a downstream port requests to serve as a host, the bus matrix couples the downstream port, coupled to the requesting device, to an upstream port of the USB hub circuit, and couples the downstream port to the automobile head unit to make the automobile head unit serve as the device.

In some embodiments, an upstream facing port device (UFP device) is connected to a DisplayPort source device via a connection that complies with the DisplayPort specifications. A downstream facing port device (DFP device) is connected to a DisplayPort sink device via a connection that complies with the DisplayPort specifications. The UFP device and the DFP device are connected via an extension medium to allow the DisplayPort source device to provide video and/or audio for presentation by the DisplayPort sink device. In some embodiments, the UFP device and/or the DFP device may be configured to provide video extracted from the DisplayPort communication to an external video processing device for processing before and/or after transmission over the extension medium.

A USB smart hub may provide enhanced battery charging, data storage security, vendor matching, device authentication, data capture/debug, and role switching. The smart hub may include an upstream port, a plurality of downstream ports, a processor, and a memory coupled to the processor for storing USB host stack code and configuration parameters. The smart hub may include a USB hub core having a core to implement a standard USB hub interface. The smart hub may include a plurality of 2:1 multiplexors coupled between the downstream ports, the core downstream ports, and the processor. The processor may control the 2:1 multiplexors. The processor may be configured to detect when a USB device is coupled to a downstream port and to run the USB host stack code and to enumerate the USB device. The processor may provide enhanced features based on the configuration parameters.

A secure, remote support platform allows secure, remote device support with an edge device (101) and a trusted intermediary server resource (“trusted server”). The trusted server (113) is an endpoint for secure connections with a support application used by a remote technician and with the edge device. The secure connections carry messages with inputs, data requests, and feedback. Messages between the trusted server and support edge device are secured in a manner that allows each endpoint to validate the messages. The remote technician controls the edge device to assesses a target device connected to the edge device. The edge device presents emulated peripheral devices to the target device while capturing the target device desktop with a camera or presents remotely controlled peripherals and returns screen captures or updates of the desktop from the target device.

A hub device and corresponding method include a first chip having at least a first upstream port and a plurality of first downstream ports, a second chip, having at least a second upstream port and at least one second downstream port; and an external memory device, storing firmware data corresponding to the first chip and the second chip. One one of the first downstream ports of the first chip is coupled to the second upstream port of the second chip to form a tiered hub, and the first chip and the second chip are sequentially enabled and the first chip and the second chip sequentially load the corresponding firmware data.
