Abstract: Electronic devices may be provided with audio circuits and controller circuitry configured to support test mode operations. A connector such as a reversible connector may be inserted into a mating device connector in an electronic device. The reversible connector may be connected to the device connector in either a normal orientation or a reversed orientation in which the reversible connector is rotated 180° with respect to the normal orientation. During test mode operations, a tester may be coupled to the device connector using the reversible connector. The tester may generate voltages, resistances, time-varying signals, or other input that directs the device to configure switching circuitry to support testing. Monitoring circuitry in the device may be used to detect input from the tester. In response to detected input from the tester, the switching circuitry may be adjusted to couple the controller to the device connector.

Abstract: An alternating current (AC) to direct current (DC) power converter may have a connector with a pair of power supply contacts and a pair of data contacts. An electronic device may be connected to the connector of the power converter. The power converter may supply DC power to the electronic device using the power supply contacts. The power converter may include control circuitry that has a resistor coupled across the data contacts. When the electronic device and the power converter are connected to each other, each may advertize to the other that capabilities are present that exceed industry standards. At the same time, standard-compliant discovery operations may be performed to probe the value of the resistance of the resistor that is coupled across the data contacts. When extended capabilities are discovered, extended functions may be performed including accelerated charging functions and data communications functions.

Abstract: Methods, systems, and apparatus for enabling a power path between a power source and a host device via an accessory. A host device may send, to an accessory arranged within the power path, via a first data pin arranged in the host device, a request for an accessory identifier. The accessory identifier identifies the accessory. The host device may then determine whether the accessory identifier is received from the accessory within a specified period of time or whether a received accessory identifier is valid. If the accessory identifier is not received from the accessory within the specified period of time, or a received accessory identifier is not valid, the host device sends a new request for the accessory identifier to the accessory via a second data pin different than the first data pin.

Abstract: Methods, systems, and apparatus for determining whether an accessory includes particular circuitry. A host device may measure a first voltage and a second voltage received from an accessory, where the voltages are provide through the accessory from a power source. Before measuring the second voltage, the host device may send an instruction to the accessory instructing the accessory to alter an impedance of the power path between the power source and the host device, and the host device may draw at least a threshold amount of current from the power source via the accessory. The host device may then determine whether the accessory includes particular circuitry based on the relationship between the first voltage and the second voltage.

Abstract: Docking stations that may facilitate the sharing or transfer of power among a portable computing device, a docking station, and an accessory. One example may provide power from an accessory to a portable computing device. Switches may be used to avoid harm from inadvertent contact with voltages on exposed terminals. Another example may provide power directly from a battery on a portable computing device to an accessory. Another may limit this direct connection to a first type of accessory. Examples may limit a power connection to another type of accessory through a regulator. Another example may power one or more internal circuits either through a portable computing device or an accessory, depending on a mode of operation of the portable computing device.

Abstract: Methods, systems, and apparatuses for booting an accessory with an accessory firmware image received from a host device are described. When the host device detects a connection between the accessory and the host device, the host device may send a request for an accessory identifier to the accessory. The accessory may send an accessory identifier to the host device in response. The host device may select an accessory firmware image that is suitable for the accessory, and may transmit the accessory firmware image to the accessory. The accessory firmware image may include information that the accessory can use to enable the accessory to exchange application data with the host device.
