This may seem like a bizarre fix but I read about someone else trying it and so having run into the issue with no Bluetooth device appearing, I gave it a try. TL;DR version, you need to install Windows 7 (or any other recent version), install the official Dell Bluetooth drivers, the adapter should switch on and become available in Windows. Once it does, reboot and install Ubuntu and the device should become available in Ubuntu.
