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.

Routing and converting traffic based on communication protocols

Multi-mode interfaces having secure alternate modes are disclosed. An example method includes exposing to a device, during a first alternate mode negotiation session, an availability of a first secure alternate mode on a host, authenticating the device to the host using the first secure alternate mode, and responsive to the device being authenticated, exposing to the device a second secure alternate mode.

Multi-mode interfaces having secure alternate modes

Input/Output port configurations using multiplexers are described herein. An example computing system includes a multiplexer having a first input, a second input, and an output. The computing system also includes a first channel connecting the first input to a first host controller, the first host controller to transfer data at a first speed, and a second channel connecting the second input to a second host controller, the second host controller to transfer data at a second speed higher than the first speed. The example computing system further includes a third channel connecting the output to a port, the port to receive a connector of an electronic device, and a line selector to, based on a type of the electronic device connected to the port, configure the multiplexer to electrically couple the output to the first input or the second input.

Input/output port configurations using multiplexers

One example of a system includes a Universal Serial Bus Type-C (USB-C) port, a set of logic circuits, a multiplexer, and an embedded controller. The set of logic circuits includes a first logic circuit providing a first utility and a second logic circuit providing a second utility different from the first utility. The multiplexer is communicatively coupled between the set of logic circuits and the USB-C port. The embedded controller controls the multiplexer to connect the first logic circuit or the second logic circuit to the USB-C port based on a value of a multi-level strap received from a device connected to the USB-C port.
