1. An electronic device comprising:
a housing;
a USB connector formed at one side of the housing and connected to a USB plug of an external device;
a high speed interface for transmitting and/or receiving data to and/or from the external device connected to the USB connector;
a voltage source for supplying a first voltage to the high speed interface;
a first circuit portion connected to a ground portion having a second voltage lower than the first voltage and having a second impedance higher than a first impedance of the high speed interface; and
a processor,
wherein the processor is configured to:
monitor the external device using the high speed interface in a first section of a first frame;
transmit and/or receive the data to and/or from the external device using the high speed interface in the first section;
connect the first circuit portion to a second circuit portion of the external device so as to form a disconnection sensing path in at least a portion of a second section other than the first section in the first frame; and
determine whether a connection between the USB connector and the USB plug is released using the disconnection sensing path,
wherein the second circuit portion has a fourth impedance higher than a third impedance of an external high speed interface of the external device.
