Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7-rc1 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

Edited /etc/init/bluetooth.conf to add -d on exec. sudo udevadm control --log-prioriry debug I am assuming the firmware or other errors explain the failure. Further Testing: Boot laptop on Windows 10 partition, both devices are discovered and work. Note: Bios has some setting to enable Wireless Switch, disable this does not help.
