It's me again.

All of USB drives does not work so far. Was not able to get them to work.
And another thing: If i turn my audio volume over ~80% my speaker give a high frequency sound that only disappears when i lower the volume. I guess it is because my microphone is always in use (i cant turn it off).
Can someone help me?

USB2 or USB3. What have you installed to enable USB3?

What driver are you using for audio?

Both. Nothing yet, because i firstly want to get USB2 to get to work.

Try latest GenericUSBXHCI.kext. Most of the time you need -gux_defer_usb2 kernel flag for Intel chipset.

VoodooHDA.

You would be better off with patched AppleHDA. Google 'patch AppleHDA guide'...
