US 2020/0004709 A1 · Adaption Apparatus, And Device Identification Method And Apparatus

Abstract

Example adaption apparatus are described. An example adaption apparatus includes a first USB interface and a second USB interface. A power signal of the first USB interface is electrically connected to a power signal of the second USB interface. A first channel configuration signal of the first USB interface is electrically connected to an ID signal of the second USB interface using a first resistor. The ID signal of the second USB interface is electrically connected to the power signal of the second USB interface using a second resistor. A resistance value of the first resistor meets a criterion followed by a first device to identify a UFP device according to the USB Type-C protocol. A sum of the resistance value of the first resistor and a resistance value of the second resistor meets a criterion followed by the first device to identify a DFP device according to the USB Type-C protocol.
