Abstract: Techniques for interacting with hardware interfaces of end devices using a hardware interface selector having a path selector, connectors, and a controller are described. The path selector may be configured to route data and to sever data communication between contacts. Connectors such as USB connectors may be coupled to the contacts and may be configured to exchange a data signal such as a USB-formatted data signal with one or more host devices and end devices. The controller may be configured to generate control signals to route data or sever data communication between contacts to cause a detection of an attachment or detachment of an end device at a host device. The controller may be configured to generate another control signal to cause transmission of the data signal from a host device to an end device. The controller may further be configured to determine whether an end device is functioning properly based on a response data signal.

Abstract: Techniques for interacting with hardware interfaces of end devices using a hardware interface selector having a path selector and a controller are described. Path selectors may be configured to be coupled to a mechanical switch, a battery, a memory, a connector or other hardware interface of an end device. The controller may be configured to generate control signals to cause a closing of the path selectors. Control signals may be configured to generate an electrical signal representing a closing of the mechanical switch, configured to cause detection of an analog signal representing a level of the battery, or configured to cause retrieval of data representing a state of the end device from the memory. The controller may determine whether an end device is functioning properly based on the level of battery, state of the end device, or other response data signals.

Abstract: Techniques for providing accessibility and testing for hardware interfaces of end devices using a hardware interface selector having a path selector and a controller are described. The path selector may be configured to route data and to sever data communication between contacts. Connector such as USB connectors, mechanical switches, and other hardware interfaces may be coupled to the contacts. The controller may be configured to generate control signals to cause detection of an attachment or detachment of an end device at a host device, or to cause transmission of an electrical signal representing a closing of a mechanical switch or another interaction with a hardware interface. The hardware interface selector may be configured to execute testing applications on host devices and end devices, and to receive alternate command signals in lieu of user interactions with hardware interfaces of an end device to execute various operations.
