Well, I finally can use my ux2 now if I open Pod Farm 2 and then open logic pro or whatever I need to use.
However, when I want to select dual inputs, like 2 mics or 2 lines at a time, my ux2 shuts down with all the usb that are plugged in.
Maybe this helps line 6 for fixing this kind of issues, it's like the ux2 doesn't have the power enough for taking two inputs at a time.
I'm writing this because my ticket doesn't have answers at all by the time, and I'm really getting fed of this, I want to use what I bought.
Oh, btw, my mbp is brand new, so that's the reason why I have 10.8.2, didn't upgrade on purpose.
