Using "lsusb -t" you may get bus topology.

It is the ethernet device, you may need to change vid/pid in dts. 

> Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. SMC9514 Hub

It is the hub device, you may need to change vid/pid in dts.

It is root hub, it doesn't need to be described at dts.
