Abstract: An operating method of a human interface device includes the steps of: counting an oversampling number of an oversampling signal and estimating an accumulated bit number of a USB data stream according to the oversampling signal; calculating a difference between the oversampling number and M times of the accumulated bit number when the accumulated bit number is larger than a predetermined value; and calibrating detected information obtained operating with the oversampling signal according to the correction parameter.
