First physical layer equipment transmits the 2nd SSIC signal that the SSIC host is sent, and the 2nd SSIC signal is turned
The 2nd PIPE3 signal is shifted to, the 2nd PIPE3 signal is transmitted to the conversion equipment by third switch；
The first PIPE3 signal and the 2nd PIPE3 signal are transmitted to second physical layer and set by the conversion equipment
It is standby；
Second physical layer equipment respectively converts the first PIPE3 signal received and the 2nd PIPE3 signal
For the first usb signal and the second usb signal, first usb signal and the second usb signal are transmitted to the USB analyzer；
Correspondingly, the analysis first signal and the second signal, determine the USB device and institute based on analysis result
State the transmission link state between host equipment, comprising: the USB analyzer analyzes first usb signal and the 2nd USB letter
Number, transmission link state is determined based on analysis result.
