It think this is the main issue.
User configuration file does not exist or is not a regular file, skipping

I've tried a lot of solutions which I found through searching my issue and none of them have worked.

1. First I tried unplugging it and plugging it back in.
2. Then I tried updating my software from .22 to 1.0.1 then back down to 1.0
3. I tried a long complicated process of updating my arduino firmware two different ways.
4. I've tried pushing the reset button 20 different ways 20 different times.
5. I updated my USB drivers using FTDI's updates.
6. I've recreated this on 2 different macs.
7. I upgraded to lion, to see if that made a difference.
8. I purchased a new arduino uno and it still doesn't work

I was able to upload sketches a few months ago.
Now I have the parts I need and I'm ready do some fun projects.
Here's the error below

Try the "tty.usbmodem431" name in the serial port list.  I'm not sure why two names show up for the same port but I use the 'tty' name.

[Reply #2 on:]

Rename your Arduino app bundle from "Arduino-1" to just "Arduino" or "Arduino 1".

[Reply #3 on:]

So I've taken your suggestions, but I haven't made any progress yet.
Here's the latest error.

Open Terminal and delete the file it is complaining about:

"rm /Users/neal/.avrduderc"

[Reply #5 on:]

Well it's saying the .avrduderc file is missing. I can create that file, but unless it's a blank file, it complains about formatting. There doesn't seem to be very much documentation about what the contents of that file should be.

[Reply #6 on:]

Oh, I just re-read your entire output.  That message has nothing to do with your problem.  avrdude doesn't use it.

You are getting the common "out of sync" error.

What kind of Arduino do you have and where did you buy it?

[Reply #7 on:]

Well I have two arduinos. THey're both unos. I forget where I bought the first one as it was almost a year ago. But that's the standard issue one.
The second Arduino is the R3 model and I bought that at radioshack. They're both giving me the same problem.

[Reply #8 on:]

Don't mess with the FTDI drivers anymore.  They don't hurt or help the Uno.  (It doesn't have a FTDI chip.)

Don't connect through a hub.

Quit the IDE, disconnect the Arduino, restart the IDE.  Does the same serial port still show up in the serial port list (it shouldn't).

[Reply #9 on:]

Well it's interesting. The standard issue uno shows up as dev/tty.usbmodem431 every time
and the uno r3 just doesn't show up at all in the serial list.

[Reply #10 on:]

So the original uno will show up as usbmodem641 if I plug it into a different physical port.

[Reply #11 on:]

Plug in the R3.

Run "System Information" found inside of Applications -> Utilities

Click on USB.  See if anything there is listed as Arduino or ATmega16u2.  If you're comfortable, maybe screenshot it (CMD-SHIFT-4 then SPACE then click on the window, saved to desktop) to show what shows up.

[Reply #12 on:]

Screen shot attached.

[Reply #13 on:]

Looks like the ATmega8u2 (or 16u2) on the other Uno stopped enumerating.

[Reply #14 on:]

So what does that mean I should do?
