An isolating transformer, like the ADUM3160 ( http://www.analog.com/en/products/interface-isolation/isolat...) should be more than overkill in protecting there.

Interesting, thanks for the pointer !

I use an Olmex isolator [1], which I believe is also based on Analog's ADuM chip. Its worth knowing that the ADuM only supports USB "Full speed" mode (12Mbit/sec) and not the normal "High Speed" mode (480Mbit/sec).
