A method of ensuring power delivery in a universal serial bus (USB) interface between a device and a counterpart device, the device including a port controller and a USB receptacle. The method includes the port controller attempting to detect an abnormal state in which a leakage current occurs in the USB receptacle using at least one pin of the USB receptacle; and when the abnormal state is detected, the port controller turning OFF a switch connected between a power pin of the USB receptacle and an internal circuit of the device, and determining to enter an unattached state of being separated from the counterpart device.
