We have a list of distributors here:

For example, Adafruit in the US:

Or the Arduino store here:

Bemused, if you're using an Olimex board, you should ask them for help.  Unfortunately, we can't support other people's products (because we don't know how they work, etc).

Does it appear in unknown devices?  Can you then update the driver?  See: and

The PDF should be the same as the Eagle files.  The two ATmel chips are different footprints for the same chip, so either can be used depending on availability.

Weird.  Did you already have those files in your /Library/Java/Extensions folder?  What if you delete them?  (The Arduino software should come with its own copy of those files.)

I'd suggest asking DFRobot for support.  It's hard for us to provide advice on other people's boards.
52  Using Arduino / Installation & Troubleshooting / Re: boards.txt wrong for Arduino Ethernet on: May 27, 2012, 05:07:49 pm
This is fixed in Arduino 1.0.1.
53  Using Arduino / Installation & Troubleshooting / Re: UNO/debian on: May 27, 2012, 06:19:44 am
You'll need a newer version of the Arduino software.  I'd suggest the recent released 1.0.1, but I think anything newer than 0020 has Uno support. 
54  Using Arduino / Installation & Troubleshooting / Re: problem installing USB drivers - FTDI on: May 27, 2012, 06:16:25 am
The Uno doesn't use the FTDI chip or drivers.  Select the top-level "drivers" folder, not the "FTDI Drivers" sub-folder, and Windows should be able to find the drivers and get the board working.
55  Using Arduino / Installation & Troubleshooting / Re: Leonardo on OSX - not in sync when uploading on: May 24, 2012, 11:12:12 am
open_market: the Leonardo isn't supported under 1.0; you don't have to try 1.0.1 if you don't want, but that's the only version that supports the board.

FalconFour: thanks for all the information.  It's a good point about not starting an upload when the bootloader is already running; I'll add that to the getting started page for the Leonardo.  On the other hand, holding down the reset button should be okay (at least, it's always worked for me).  If I'm having problems uploading normally, I'll hold down the reset button, wait for the IDE to say "Uploading..." and then release the button.  Can you provide some more details about the problems you're having with holding the button down (e.g. when are you doing it, what exactly happens, which operating system you're using, etc)?
56  Using Arduino / Installation & Troubleshooting / Re: Leonardo on OSX - not in sync when uploading on: May 23, 2012, 09:43:59 am
BTW, we expect the application (sketch) COM port to be different than the bootloader COM port.  The upload process takes that into account (it waits for the sketch COM port to disappear and for any new COM to appear, assuming it's the bootloader).  If you have better luck by forcing them to be the same, that sounds good to me.  Just wanted to let you know that it's not necessarily a problem that they have different numbers.

And yes, my guess is that KEY_F4 is an int, and so print() tries to print its digits rather than sending it as a single key press.  The write() function always tries to send a single key press (or a single byte, if you're using Serial).
57  Development / Suggestions for the Arduino Project / Re: Option to Not include all the USB libraries (Leonardo & compatibles) on: May 23, 2012, 09:38:35 am
In the future, we'd like to find a way to control which USB libraries / classes / capabilities are loaded in a sketch.  In particular, we'd like to avoid loading the HID (mouse and keyboard) support if you don't use it - allowing for other USB classes on those endpoints.  Currently, there's a Mouse.begin() and Keyboard.begin() function; ideally, if you didn't call those, the Mouse and Keyboard classes wouldn't be loaded (avoided both the flash and endpoint usage).  The hope is to change the core in the future to work that way.  We try to avoid using preferences in the boards.txt file to control things that aren't actually related to the board (otherwise, the number of boards needed would expand exponentially as you added preferences). 

As you say, CDC is used for the auto-reset, so we might not disable that by default.
58  Using Arduino / Installation & Troubleshooting / Re: Arduino Nano isn't working well with Baud rate 9600 bps, why? on: May 22, 2012, 11:44:18 am
Nick, I think it might be the opposite.  That is, the board is probably running at 16 MHz but the code is being compiled for 8 MHz.  So when you say Serial.begin(9600), you're actually getting 19200 baud. 

bigthunder, are you sure you have the right item selected in the boards menu?
59  Using Arduino / Installation & Troubleshooting / Re: avrdude: stk500_getsync(): not in sync: resp=0x00 Error on: May 22, 2012, 11:42:11 am
What board are you using?  And what's the full name of the board menu item you have selected?

Also, definitely check out the troubleshooting guide.
60  Using Arduino / Installation & Troubleshooting / Re: Arduino Mini w/ 328 problems on: May 22, 2012, 11:39:56 am
The Mini comes with a bootloader on it and you should be able to get it to work without burning a new one.

You might try with Arduino 1.0.1 (just released).  We updated the avrdude programmer type used to upload the sketch to the Mini, which should make the auto-reset work more reliably.
