Rys,
I do have one request of you, and that's when all is said and done, and if they can fix it without replacing it, please let us know what was wrong with it.

I'm going to ask you one other thing. There is a BIOS update for this which resolves a USB 3.0 issue, but since the AudioBox is USB 1.1 is shouldn't matter.
BUT, on the rear of the unit, there are two sets of USB ports. Two of them sit next to the two more, which are sitting next to the Ethernet port. The two that are alone are USB 3.0/2.0. (These should be the blue ones) The other two are USB 2.0/1.1.(These should be the red ones) These are the one that are sitting with the Ethernet port. The AudioBox is a USB 1.1 device. Which USB port are you using??? In this case, it may very VERY important. You want to use the red ones!

I want to go back and expand on this a bit. There are three headers on the mainboard for external USB 2.0/1.1 connectors, like you'd have on your case. If the case is connected to them, I would try the Prosonus in one of those USB connectors. The USB 3.0 standard is supposed to run at up to 5Gb/s versus 480Mb/s for USB 2.0, and electrical noise is a real possibility in audio. Plus, instead of the standard four pins for the lower rates, you have 8 or 9 for USB 3.0. There is a chance that the cable is picking up spurious signals from those other pins, which would cause all sorts of noise.

Sorry I didn't notice this earlier.

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
