Yeah sure it is a help to everyone. What I was trying to
figure out for my further education is how these ports
when opened by the device plugged in and installed
were named in /dev/. Tom pretty much had the answer.
I'm a very avid linux user and was comparing the port
device name be it USB, SATA, Firewire, PCIe etc..
So it seemed a bit odd to to have the enumerated
USB to serial device to convey an actual name from
the driver developer rather than a standard name
that linux uses. Occasionally I have to remind myself
that OSX 10.8.2 is now unix and not linux and while
very similar, still possess differences as in this port
name convention.

All that stuff below is completely foreign to me, but I wanted you to know that on my MAC, my (working perfectly) port is
/dev/cu.PL2303-0000203A I have no idea if that helps at all...

Thanks for the info, I still have a Windows 7 netbook,

But my main computer is the 2011 MacBook 15.4" quad.
I love the unix OS. Spent a decade supporting SCO and BSD
and Novell 3xx and 4xx. Started out when networks were Thomas
Conrad 100 mbps coax on DOS and business software from IBM
and Macola.
Fun stuff but I was not involved in any coding other than being an
official beta for NT4. So I love learning and asking questions as you might
have guessed by now.

I assumed it was a name the system issued a USB to serial port device
and not reflected of the driver name.
On Linux, udev usually chooses the device name. On OS X, the driver
tells the OS what name it wants.
FTDI usually shows up as /dev/cu.usbserial-xxxxxxxx, where xxxxxxxx is
either the device's serial number or, for unserialized devices, a
location string that depends on which USB port your device is
connected to.
The Prolific PL2303 driver enumerates devices at /dev/cu.usbserial.
I think /dev/cu.PL2303-XXXXXXXX is associated with the open source
PL2303 project.
