I don't know if you posted before you finished or forgot to crtl+z, but there isn't anything there.
I'm guessing you're thinking about the front USB. If so, I've copied games from front USB to back USB (0/1), but never tried Wii U games in F-USB (port 2/3?). I can tell you HB stuff can load from the front, but Wii U games might be an issue.
