1. An interface device comprising:
a plurality of ports configured to form a plurality of lanes; and
a link controller configured to set a speed of a link including the plurality of lanes by determining the speed of the link based on a state of the link before entering into a configuration state of the link among a plurality of states of the link,
wherein the link controller is further configured to set, when the link enters into an L0 state from the configuration state among the plurality of states of the link, the speed of the link to a first one of first and second speeds in response to a speed change variable having a first value, the second speed being higher than the first speed.
