PROBLEM TO BE SOLVED: To provide a serial bus processing method and a serial bus-processing device for normally transmitting or receiving data by avoiding loop connection by automatically recognizing the loop connection. SOLUTION: In the serial bus processing method in the serial bus processing device, loop connection that is composed in a serial bus is detected, according to steps S11-S18 to automatically avoid the loop connection, a timer value having a random value is set according to the number of ports that cannot be recognized each node, when detecting the loop connection, and a port is made invalid and a cable is disconnected virtually when the set timer value is reached, thus composing a new bus topology automatically.
