I have a Pod Studio UX2. It's a great piece of equipment. I bought a Macbook Pro Retina with Mountain Lion about 2 months ago. I installed all of my line6 stuff onto the new computer, updated all the drivers and thought I was good to go. About 5 minutes into recording I heard a very loud pop. I looked over at my UX2 and both clipping lights were on. All of the other lights were out. But not only did it kill the UX2, my mouse stopped working, which was plugged in to another USB port on my computer. In order to fix this I have to either restart my computer or unplug all USB devices, shut the lid so it can go to sleep, wait for about 30 secs and open the lid. Somehow this resets the USB ports I guess.

It's not only when I'm recording though. It will do it when I am just using it as an audio card. It's as if when I do something on my computer that needs audio to work it sometimes does and sometimes makes that loud clipping sound and kills all USB ports. It makes it really hard to do any audio work of any type...

I also get random crackling sounds when recording no matter what the buffer size is set to. It's like a very distorted reverb / delay sound. It lasts for about 3 - 5 seconds then cleans up again.

Is there anyone else having this same issue? If so, have you found a solution to this or a workaround? I've been talking with tech support, but they said they had not heard of all USB ports dying like mine are doing.

Mac put out an update a few weeks back that was suppose to update USB drivers for "certain applications" but unfortunately that didn't solve the problem.

I'm running Mountain Lion 10.8.2 Intel Core i7 2.6 GHz with 16 GB of memory.

I have many other USB peripherals that work without issue which lead me to believe that it's not the hardware itself.

Thanks in advance for any help!
