Abstract: A dongle includes an upstream facing Universal Serial Bus (USB) Type-C port and a downstream facing USB Type-C port. The dongle also includes a security processor communicatively coupled between the upstream facing USB Type-C port and the downstream facing USB Type-C port. The security processor is to, with the upstream facing USB Type-C port connected to a host and the downstream facing USB Type-C port connected to a device, authenticate the dongle in response to an authentication initiation request from the host.

Abstract: 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.

Abstract: 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.

Abstract: An example system includes a portable storage device carrier to receive a plurality of drive trays. Each of the plurality of drive trays receives a storage device. The example system further includes a dock assembly to receive the portable storage device carrier. The dock assembly includes a circuit assembly to electrically couple the storage devices to a computing device.

Abstract: 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.

Abstract: An example device includes a port to receive a connector; at least two functions accessible through the port; and a controller coupled to the port. The controller includes an orientation detection portion to determine an orientation of the connector when received by the port, the orientation being one orientation of at least two possible orientations in which the connector may be received by the port; and a function selection portion to select, based on the determined orientation, at least one function of the at least two functions to be made accessible through the connector.
