In operation 407, the electronic device (e.g., the identification circuit 130 or the processor) may request to turn on a USB host operation. For example, it is possible to request the identification circuit 130 or the USB controller 111 to turn on the USB host operation. For example, the identification circuit 130 may transmit a host turn-on request message to the processor or the USB controller 111.
In operation 409, in response to the host turn-on request message, the electronic device (e.g., the processor or the USB controller 111) may turn on a host function. The USB controller 111 may turn on a host function. The processor may perform control such that the USB controller 111 turns on the host function. The USB controller 111 may include a host block that performs the host function.
