Hi all!
I'm having some issues on USB. They're working, but if I tried to record into my USB microphone I have some glitches/freeze in recorded audio. Also If I turn on my printer, my USB Hdd turns off :( .... I think it's a problem with USB Map.
I tried to follow the guide on Dortania, but I lost myself after a while... sorry I'm a total newbie.

Please, anyone have the USB map files for my Mobo? How can I integrate into my EFI folder?

Thank you so much... I'm banging my head for days!! :(
