I just received an FTDI Friend from Adafruit, and when I plug it in via USB it doesn't show up in my terminal when I type "ls /dev/cu.*". The only two things that show up are "/dev/cu.Bluetooth-Modem" and "/dev/cu.Bluetooth-PDA-Sync". I'm on a mac (obviously).
I've tried three different USB cables with the same result. Any ideas as to what I might be doing wrong?
