For the specific setting of the host, reference may be made to the setting of the host in the above embodiments, and details are not described herein.
Specifically, when the connection response request is generated according to the number information, the master controller first obtains the interface number of the communication bus interface on the communication controller, determines the number information of the accessed slave according to the interface number of each communication bus interface, and generates the connection response request carrying the number information.
For example, when the communication bus interface with the interface number 0 is accessed to a slave, the corresponding slave is the first slave, and the slave number of the slave can be determined to be 0, the number information is determined to be "0", and a connection response request carrying the number information is generated. Correspondingly, when the communication bus interface with the interface number of 1 is accessed to the slave, the corresponding slave is the second slave, the slave number of the slave can be determined to be 1, the number information is determined to be 1, and a connection response request carrying the number information is generated.

Further, after receiving the connection response request, the slave controller of the slave device may analyze the connection response request and obtain the number information therein, determine the slave device number according to the number information, and generate the connection confirmation information.
For example, the master controller sends a connection response request carrying number information "1" through the communication bus interface with interface number 1, and the connection response request is sent to the slave controller of the second slave computer after passing through the first connector endpoint with host endpoint number 1, the second connector endpoint with first slave endpoint number 1, and the first connector endpoint with first slave endpoint number 1 to reach the second connector endpoint with second slave endpoint number 0.
Further, the slave controller analyzes the connection response request to obtain number information "1", determines its own slave number according to the number information, and generates connection confirmation information.
After the slave computer generates the connection confirmation information, the slave controller of the second slave computer returns the connection confirmation information to the master controller of the master computer through the second connector end point with the end point number of 0, the first connector end point with the end point number of 1 of the first slave computer, the second connector end point with the end point number of 1 of the first slave computer and the first connector end point with the end point number of 1 of the master computer.
