USB Powered EEG - USB provides 1 MOPP want 2 MOPP

NHaman

From doing some reading, it seems that USB provides 1 MOPP. If this is correct and I have isolated the USB port to 4kV, then do I comply with 2 MOPPs?

If this is not correct, then what steps can I take to provide the 2 MOPP? Is it as simple as having 2 isolated power supplies in series?
