I'm having the same Fn problem!!!! I'm not trying to hijack your thread but is this the same thing it says to you? Every time I open EFI it says (EFILive USB drivers have not been installed. No connection with FashScan is possible until the EFILive USB drivers are installed).
What I don't get is as i am typing this It's hooked up to the freaking computer. Oh and I also have Windows7.
