Note: this is not a question on the progress of the USB stack (which is forbidden by the forum rules), just general questions:
1. What exactly should the USB do? Should it provide a connection to a computer, so you can copy your music to it without having to enter the OF? Or should it be USB OTG, so you can use USB sticks and cameras without a computer?
2. From the commits to the SVN, it seems to me only PP targets are supported. Is this true?
