Different v4l ports on two upboardes

I've bought 4 up boards and connected to each one two cameras.
I've tried to read their usb port using "ls -l /dev/v4l/by-path".
Two of the upboard give the same results - i.e the cameras that were connected on the same usb port got the same name, ao the other two it was upside down.
Eventually I have the same code running on the 4 of them and I need one static address for the 4 of them corresponding to the usb port they were connected to.
Does anybody what can it be?
