Help with Device Connections on Nano v. 3

edited October 2013 in Arduino

I am using Processing 2.0.3 and the Arduino boards as discussed below. When I use my Uno board and print out the Arduino.list(), I get these devices:

[0] "/dev/tty.Bluetooth-Serial-1" [1] "/dev/cu.Bluetooth-Serial-1" [2] "/dev/tty.Bluetooth-Serial-2" [3] "/dev/cu.Bluetooth-Serial-2" [4] "/dev/tty.Bluetooth-Modem" [5] "/dev/cu.Bluetooth-Modem" [6] "/dev/tty.Bluetooth-PDA-Sync" [7] "/dev/cu.Bluetooth-PDA-Sync" [8] "/dev/tty.usbmodem14221" [9] "/dev/cu.usbmodem14221"

I can set my Arduino object to list item [8] and my program works fine.

However, when I switch to the Nano v. 3 board and list my devices, I get this:

[0] "/dev/tty.Bluetooth-Serial-1" [1] "/dev/cu.Bluetooth-Serial-1" [2] "/dev/tty.Bluetooth-Serial-2" [3] "/dev/cu.Bluetooth-Serial-2" [4] "/dev/tty.Bluetooth-Modem" [5] "/dev/cu.Bluetooth-Modem" [6] "/dev/tty.Bluetooth-PDA-Sync" [7] "/dev/cu.Bluetooth-PDA-Sync" Experimental: JNI_OnLoad called.

There is no "dev/tty.usbmodem14221" listed and so my sketch does not work.

Can anyone shed light on why I'm not showing the device I need?

MacMini, OS X 10.8.5.
