The adapter includes a first USB type-C controller, a second USB type-C controller and pleural USB type-C data transmission lanes connected to the second USB type-C controller and the first USB type-C controller. The second USB type-C controller is configured to: (1) obtain a first transmission specification supported by the second electronic device; and (2) transmit the first transmission specification to the first USB type-C controller. The first USB type-C controller transmits the first transmission specification to the first electronic device. The first electronic device transmits a control command to the first USB type-C controller according to the first transmission specification. The first USB type-C controller further uses a corresponding number of data transmission lanes according to the control command. ## Claims ### Claim 1 An adapter configured to transmit signal of a first electronic device to a second electronic device, the adapter comprising: a first universal serial bus (USB) type-C controller configured to electrically couple the first electronic device;
