How to figure it out the USB path

I add an iphone to the Mac Mini and assign it to the guest OS. I saw:

usb.autoConnect.device0 = "path:10/1/1/2/4/3 autoclean:0"

in the *.vmx file. I plugin in a second iphone to the device, it will generate a different path. Is there a way to find out the path: X/Y/Z/A/B/C after I plugin a new iPhone?

Thanks
