I think I may have misunderstood your intent. I thought you wanted to be able to press the menu button (normally assigned to M on your keyboard) on the home screen and you jump straight to your removable storage. But am I to understand it that you'd actually like a button to appear on the home screen (like Movies, Games, Music, etc...) called USB Play that when pressed jumps straight to your removable storage?

You mentioned your not entirely sure of how to specify the path info to your removable storage. As I don't use Linux based systems and the like, I don't know what it'd be. But you can sort of "cheat". Go to your removable storage and save it as a favourite in Kodi. Then using your file system, navigate to your kodi/userdata directory and open the favourites.xml in there. The appropriate ActivateWindow command with the path info will be stored there.

I'll look at the PIN issue you mention shortly.

I'll also look at fixing all the niggling issues reported by people that affects Mimic on Kodi Leia in the release after next for Lyrebird.
