USB 2.0 isolator, this thing works!

I might have to look into these.
I have a few signal loops in my system and occasionally get a high pitched digital noise. I can usually reduce it by unplugging and roughing replugging the USB devices but this might help.

I go from instrument to ABY pedal into guitar and bass amps.... DI out of each amp into looper pedal, into Ui24 mixer/interface. The Ui24 goes into computer for recording when needed which then (when playing sound from the computer) goes back through a Focusrite interface into the Ui24 mixer and into some bookshelf monitors. The guitar amp (Boss Katana) also goes back to the computer via USB.

Friends, this device heats up quickly, now I understand why customer service says not to use it for long hours during the day.
