Support USB hub like stock IOS58

[msSeven]

Would it be possible to implement support for USB hubs in the same way that stock IOS58 does? It's not that important on a regular Wii, but with the Wii Mini only having one USB port it would be convenient to be able to run games from USB while also being connected to an ethernet adapter. This would allow us to play backup games online on a Mini.

That is on my to-do list, but unfortunately I don't really have any time for cIOS development with all my other projects (Wiimmfi, LE-CODE) so I have absolutely no idea when I'll get to that.
