[Collin Cunningham] explains USB protocol and manages to connect a USB MIDI keyboard to Arduino using Cirtcuits@home USB Shield.

USB devices are so common nowadays – wouldn’t it be nice to use one with your homebrew electronics projects? I wanted to use my compact USB-MIDI keyboard with my homebrew synth circuits. It seemed a simple enough prospect at first – listen to the data output, press buttons, note the changes, and then program a microcontroller to turn those changes into something I could use (like basic serial MIDI data).
