1. An electronic device comprising:
an application processor internally comprising both a first embedded universal serial bus (eUSB) device configured to perform an eUSB function, and a processor configured to control the first eUSB device;
a repeater configured to be electrically connectable between the first eUSB device and an external device; and
an identification circuit separately coupled to the application processor, the repeater, and the external device;
wherein the processor is configured to:
monitor to detect a connection of the external device to the electronic device,
identify a mode related to an operation speed of the external device, and
based on the identification that the mode is a full speed (FS) mode or a low speed (LS) mode, control a first signal to be transmitted or received in a high speed (HS) mode between the first eUSB device and the repeater by controlling the repeater to operate in the HS mode through a reset signal and a second signal to be transmitted or received between the repeater and the external device in the identified FS mode or LS mode.
