1. A method of synchronization in a training state for Universal Serial Bus (USB), comprising:
sending SLOS1 ordered sets by a transmitter in a LOCK1 state;
receiving the SLOS1 ordered sets by a receiver in the LOCK1 state;
stopping the transmitter from sending training ordered sets according to a lane adapter state machine (LASM) if the transmitter sends the training ordered sets in the LOCK1 state continuously in an infinite loop, the training ordered sets comprising the SLOS1 ordered sets;
sending new SLOS1 ordered sets by the transmitter, a length of the new SLOS1 ordered sets being different from a length of the SLOS1 ordered sets;
receiving the new SLOS1 ordered sets by a receiver; and
the transmitter and the receiver entering a LOCK2 state.
