No options for USB Serial Port on OSX

Development Tools IDE 1.x

Hi-
I saw this was covered in Jan 2010 http://arduino.cc/forum/index.php/topic,28259.0.html but never successfully answered and I have a similar problem in 2011. I am just setting up my new Arduino Uno. When I connect it to a Macbook Pro running 10.6.6 and attempt to choose a serial port using the Arduino app the only options I get are: /dev/cu.usbmodem3d11, and the same config for Bluetooth PDA or Bluetooth Modem. These three choices show up as tty options as well.

The green LED is on, the yellow is blinking.
I have restarted the computer.
I have tried three different USB cables.
I have tried a different USB port.
I have the official Arduino Uno, not a knock-off.
I checked all the lands for solder splatters &c, but everything looks clean.

When I first plug in the Arduino board a window pops up saying a new network interface has been detected. If I go to network preferences I see the Arduino name with a telephone icon next to it. No serial interface options are offered here either.

The download window showed just one driver option, which didn't mention Intel in the name (as I read in my Getting Started" book), so to explore one more possibility I loaded the software on a non-Intel G-5 running 10.4. I also connected the board through a powered USB hub. I had the same problem, save that the modem options were the only ones available as the G-5 doesn't have a Bluetooth card.

Could it really be the board? Thanks in advance for any help you can give me with this.

"/dev/cu.usbmodem3d11" is the Uno. There should also be a "/dev/tty.usbmodem3d11" in the list as well.

Yes, the Uno appears to OS X as a USB Modem. There are no settings you need to change in the Network System Preference panel. Nothing in that window has to do with the Uno (except for the device being there.)

There are no drivers to install. The Uno emulates a USB Modem so that you don't need to install any.

Excellent! Thank you so much. I just sketched out the blinking LED to try your solution and it worked. I was fixated on the illustration in the book, and reading the choice backwards! I've been busy with work and unable to start exploring the Arduino for the past week. Now I may go all night! Thanks again.
