Zusammenfassung:A universal serial bus (USB) system is provided. The USB system includes a master device, a bus and a slave device. The bus is configured to transmit the signals that comply with USB standard. The slave device is coupled to the master device through the bus. When an interrupt event corresponding to low frequency periodic signaling (LFPS) of the slave device is received through the bus, the master device and the slave device execute a LFPS handshake procedure to make the slave device enter a link recovery state.
