I have done some research and I am pretty sure it is due to the use of TS cables instead of trs to connect the stomp to the monitors. The unbalanced cables create a ground loop when connected via usb. Can it be that?

Hi guys, I just bought an hx stomp and I am so happy with the sounds I can get out of it. I am using it with studio monitors (M-audio bx5 d3) and it works well. The only problem that I have is that when I plug the stomp to my computer via usb it makes noise. Since it only makes that noise when plugged with usb I know thr cables or the monitors are not the problem. If anyone knows how to fix it let me know cause it is a little bit annoying. Thanks in advanced.
