There is a question saying that their USB, WiFi and Bluetooth are all broken since the upgrade to 15.10 from 15.04.
Are these multiple questions (because it's 3 different things), or should it be left as one (because they were all caused by the same thing)?
I'm also predicting that these questions are going to arise more with the 15.10 update - it seems to be causing multiple issues in a lot of cases.
