Mbox 2 -CoreAudio Manager Unsupported device not c

[DTM]

Hey people.

I have had a lot of trouble with pops and crackles when using Pro Tools or any other audio app for that matter through my Mbox 2.

When trying to isolate the problem, I noticed that when I open the CoreAudio Manager it shows "Unsupported device" "Not connected (HW not found)"

Is this normal for M Box 2?

I think the crackles and pops I get are related to CoreAudio or MBox 2 as I can get rid of the crackles in Ableton live by not using the Core Audio just using Mac inbuilt audio out.

I am totally sick of not being able to use my Mbox 2 without the this crackle and popping. Please if anyone has any suggestions let me know.

I have tried Digidesign and they said it might be compatibility but I am fully qualified...

Thanks in advance to anyone with some suggestions.
