I have reinstalled Ubuntu 16.04 afresh today and after a complete update this is still an issue with my Cambridge Audio USB soundcard. Removing fwupd did do the trick this time. However if I was new to Linux this wouldn't give a good first impression and indeed could have been a deal breaker. I noticed there was an update to fwupd whilst I was updating the system; but as I said this didn't work for me.
