I assume you are powering the Pi from the power supply directly? (rather than via the USB hub)
If you don't connect the powered hub presumably the UV message doesn't occur?
Currently, I cut a usb cable and connected that to the power supply and plug into the micro usb port on the Rpi, I have just purchased shim to allow me to power to the gpio pins directly (the shim is to provide the circuit protection you get from micro usb port).
That will eliminate the USB cable as a culprit. I hope that solves it.
No I get UV messages regardless of the hub being connected or not. Mind you I do have to plug the keyboard fob and the ocharts dongle directly into the rpi then, so maybe not a fair statement...
Thanks for your suggestion about the cable

I will eliminate the cable and go directly to the GPIO then. Last resort!
