Abstract: A method for link transition in a USB device includes transmitting a plurality of first RS-FEC blocks by a first transmitter, receiving an UNBOND set by a receiver, waking up a second transmitter by a LASM when the receiver receives the UNBOND set, transmitting a training sequence by the second transmitter, transmitting a specific pattern sequence by the second transmitter after finishing transmitting the training sequence, determining whether a current RS-FEC block to be transmitted by the first transmitter is a DESKEW block, stopping transmitting the specific pattern sequence if the current RS-FEC block is determined to be the DESKEW block, and transmitting a plurality of second RS-FEC blocks by the first transmitter and the second transmitter.

Abstract: A method of synchronization in a training state of Universal Serial Bus (USB) includes 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 include the SLOS1 ordered sets. The method further includes sending new SLOS1 ordered sets by the transmitter, receiving the new SLOS1 ordered sets by a receiver, and the transmitter and the receiver entering a LOCK2 state. The length of the new SLOS1 ordered sets is different from the length of the SLOS1 ordered sets.

Abstract: A method for link transitions in a Universal Serial Bus system includes transmitting a plurality of first RS-FEC blocks by a first transmitter of the USB system, transmitting a training sequence by a second transmitter of the USB system, determining number of sets in a first RS-FEC block which have been transmitted by the first transmitter when the second transmitter completes transmitting the training sequence, generating a specific pattern sequence according to the number of sets in the first RS-FEC block which have been transmitted by the first transmitter and a total number of sets in the first RS-FEC block, and transmitting the specific pattern sequence by the second transmitter.
