Control a Kuando BusyLight with Arduino


I have a Kuando UC Omega Busylight.

The Busylight has a RGB-LED and is designed to change color according to the status in Lync, Skype or Jabber running on a PC.

I would like to control the color with a push button and, when possible, display more different colors.

So I thought to use an Arduino with a USB-host shield to connect the Busylight to.

There are lots of projects were for example a USB game controller is used as input on a USB-port and controls a game or servo.

But I'm looking for a sketch that sends data from the USB host to the buisylight (a USB-accessoire).

Is there someone who can help me with this project or has already made something like this?
