If anyone's interested, I got their firmware to run on stock Arduino hardware (which costs $55 instead of $390). http://romfont.com/2011/05/12/google%E2%80%99s

It's looking good so far. Now all I need is a device that supports accessory mode ...

Heh, me too--how long did it take you to write up your post? It would've been useful, ah, 8 hours ago. :) I've tested a revision 1 SparkFun USB Host shield and UNO/Duo with pin define fixes and a Nexus One with Android 2.3.4 and the DemoKit app. It "works" but seems a bit flakey needing multiple resets to move from detecting to data transfer. I'm suspecting possible power related reset issues. Unfortunately my usual laptop is in the shop so I haven't documented this as I'd normally like. Will take a look at what you've patched but first need to get some sleep. :) Edit: Actually, it seems much more reliable when the Arduino is connected only to a 9V battery and not USB as well.

  Hah, I got it working yesterday but I had other stuff to do and I wanted to patch their code to work on both 168/328p and 1280/2560 before doing a proper write up. Can you test my patch and get back to me whether it works for you? That way I can update my post.

    Have checked your patch and commented here: http://romfont.com/2011/05/12/google%E2%80%99s-open-accessory-development-kit-on-standard-arduino-hardware/#comment-31 http://romfont.com/2011/05/12/google%E2%80%99s-open-accessor... Have also put up some photos of input/output example of Arduino Uno + Usb Host Shield + Nexus One here along with some code: http://rancidbacon.com/p/android-arduino-accessory/ http://rancidbacon.com/p/android-arduino-accessory/
