Abstract
Disclosed is an electronic device including: a USB connector connected to a USB plug of an external device; a high-speed interface; a voltage source for supplying a voltage to the high-speed interface; a first circuit portion connected to a ground portion, and has a second impedance higher than a first impedance of the high-speed interface; and a processor. The processor is configured to monitor the external device by using the high-speed interface in a first interval of a first frame, form a disconnection sensing path by forming a connection between the first circuit portion and a second circuit portion of the external device, and use the disconnection sensing path to determine whether the connection between the USB connector and the USB plug has been disconnected. The second circuit portion may have a fourth impedance higher than a third impedance of an external high-speed interface. Various other embodiments are also possible.
