Zusammenfassung:	The present invention discloses a method of getting out from error entering into test mode in USB3.0 apparatus, in which extra status states are inserted into the compliance mode in the original state diagram of the link training and status state machine of the conventional USB3.0 protocol. The inserting status states are to set up a timer, and go to power saving state U1, U2, or U3 or SS.Disable state when timeout happens. The insertion of the timer will not change the normal compliance tests required by the conventional USB3.0 protocol because a Ping.LFPS will always force the state go from power saving state U1, U2 or U3 to compliance mode, and the Ping.LFPS is always needed in normal compliance tests.
