ASUS Z97 Pro (Wi-fi) Bluetooth module won't start

[545646674116]

 ASUS Z97 Pro (WiFi) /Bluetooth module won't initialize.  The On-board WiFi and Bluetooth are contained in the same module  The WiFi is working fine, however the Bluetooth, no matter what I do will not start. It had been working fine, and my phone showed paired. I've tried to let Windows 10 install the Microsoft drivers, I've used the ASUS drivers, but the result is always the same (all Bluetooth services are running and have been restarted) - it will not initialize. I guess the Bluetooth component of the module could be dead, but one would think it's an all or none situation. In the device manager this is the error I get (see above). Any insights would be appreciated. In the end it's not a huge deal as I really never used the Bluetooth anyway, and if I can't get it fixed I'll just turn it off in the Bios.
