MAXOSX : how to find out which port /dev/## the USB use

In my case, I try to connect a EspressoBin on my MACintosh, but I'm not able to find which port is using or connected to.

But it is for every possible USB, how to detect which port /dev/### it uses

Via command line, I'm able to find back the name of the vendor, the ID of the Vendor and product;

$ system_profiler 
$ system_profiler SPUSBDataType

        USB-Serial Controller D:

          Product ID: 0x2303 / 0x2303(16) = 8963(10)
          Vendor ID: 0x067b  (Prolific Technology, Inc.)
		 /  0x067b(16) –  1659(10)
          Version: 4.00

          Manufacturer: Prolific Technology Inc.

Is there a possibility to write a similar script to figure out which port is used.
