I know this thread is slightly stale, but it also seems to be the closest thing I can find to the official thread for the LaunchPad.

In as much as I can see that the LaunchPad successfully implements "Output" as well as Input, I have a question.

It is not so much that I am trying to create competition for the LaunchPad, but I am trying to help increase innovation. What I would like to know is, how does the LaunchPad parse the "Output Reports" sent from the DS to the "USB HID" device that the LaunchPad is acting as?

I have done a lot of searching on the Internet and have found almost nothing on the formatting of "output reports" let alone any examples of how to receive and parse these reports.

Specifically I have two devices I would like to use in the exact same manner as the LaunchPad, the Teensy 3.1 and the Leonardo. Thus far. using them as input devices is all I can achieve. It's the output, such as turning on LEDs or force feedback, that I can not seem to be able to do.

I guess there is a second question I would like answered. Is there a document that includes a description of the data formatting sent by the DS to attached USB HID devices?
