Interference/Noise when connecting to Live via USB

Hello there!

I am having problems when syncing my MiniBrute to Ableton via USB. I am connecting it via USB so that it syncs with the bpm of the project. All that is fine. The problem is I get a loud interference noise. This noise is only present when the USB is connected and, strangely, still persists even when the MiniBrute is switched/powered off and unplugged from the power supply.

Below are a list of things I have tried/troubleshooted so we can scratch them off;
-MiniBrute directly connected to Mbox via instrument cable is fine (as are guitars, basses, mics, etc)
-Noise still there even when MiniBrute is switched off, only disappears when USB is unplugged
-Tried 2 different USB cables (including shielded), same problem
-Noise problem also occurred in Ableton 8 (recently upgraded to 9)
-Tried in a different room with different power outlet, same problem.
-Have APC40 connected via USB, no problems there.
Any help on this matter would be greatly appreciated, I bought the MiniBrute specifically for work on a new project with Ableton and this is really holding things up!
I've included a small sample of the noise (with some notes on the synth played over it)

Thanks guys!
