USB Ground Lift

I’m not sure if this is possible or not, but it’d be nice to be able to lift the ground for the USB connection. Since my computer is on a different circuit, I find that I get a ground loop when running into a physical amp while connected via USB.

Cutting a piece of electrical tape to size and putting it over the ground pin on the USB cable eliminates the hum, but makes the USB connection a bit unreliable when using Cortex Control. Weirdly, it seems like completely blocking power causes Cortex Control to no longer properly launch, it gets hung up on “Loading Preset”.

The grounding noise issues with the QC are wild. Even had the issue with the QC and laptop plugged into the same circuit. For some reason I get a crazy ground noise if I’m using my laptops charger with it
