[Gamecube specific]

Browse Source 
---------------
* fixed audio input frequency, now use exact audio hardware samplerate, as measured on my Game Cube (~48044 Hz),

[Wii specific]
---------------
* fixed USB drive not being detected when application is loaded from USB (HBC), thanks to Tantric for the tips.
