How do you use the Arduino USB_host library?
I want to read the data from a usb midi keyboard (Korg microKey) on my Arduino (Arduino Mega ADK), but I cannot find any tutorials on how to use the USB_host library for this kind of application. There are also no tutorials that explain how the USB_host library works, so I cannot work out the code for myself.
An example of what I wan to do can be found here: https://www.youtube.com/watch?v=kfCDjwHBBuM. However, he does not explain how he does it, or how how to adapt his code for other devices.
