Can I just add that this affects my Cambridge Audio DAC Magic100 also. I have found that it seems to effect Ubuntu and Ubuntu mate but strangely not Kubuntu. I tried Ubuntu again 3 days ago and this is still a problem. In fact as I get small shocks from the case I'm a little reluctant to pursue this further. I note killing fwupd solves the issue which is interesting as it doesn't seem to work for Kubuntu.... Maybe off by default?
