What for? Isn't it simpler to isolate the part of the circuit that really needs to be isolated? Who cares if the USB side itself isn't?
Maybe isolate only USB chip (like USBN.....) with 3 optron (RXD TXD CLK) is more simply that USB?

If you're using a separate USB tranceiver (Philips makes them) then you can isolate between that and the USB controller using a magnetic isolator (high speed compared to opto) and bus-power the transceiver. This works for full speed. For high speed, you'd need to isolate a much wider bus so the isolation will be more expensive. I haven't tried that.
