Just to complicate matters, I had the same error message last night with the STi connected, via a 3 metre USB cable, to a native USB3 Port on my ASUS Notebook. I then unplugged the STi cable from that USB3 Port and inserted it into the adjacent native USB3 Port and voila, the STi recovered and worked flawlessly all night.
It seems there are (native) USB3 Ports and then (native) USB3 Ports!
As Paul mentioned previously, Power Management has been disabled for all USB Root Hubs.
