> So this KeyStep I just got seems to pick up all kinds of noise when the USB cable is plugged into the computer (or a hub connected to the computer). If I power it using the USB cable plugged into a powered hub not connected to the computer it’s fine, it’s quiet. Has anyone else seen this?

It does sound like you may have a similar ground loop problem, if so you could try a ground isolator of the kind mentioned there.
