Under Windows, if devices have a serial number, then this number MUST 
be unique, otherwise they won't install correctly.

The lastest version provides some information about bus topology but
this code will be removed in the future since it doesn't work properly.

Apart from that, even if you were able the retrieve the correct bus and 
port
number of your device you still can't keep the devices apart. 
Why? Because there is no way to correlate these numbers with your physical
hub or bus ports.

So the only way the distinguish between two identical devices are serial 
numbers.
