2015 Retina MacBook Pro and Bluetooth

I have upgraded from a 2010 MacBook Air to a 2015 retina MacBook Pro, both with OS X 10.10.2, and restored from the Air backup via Time Machine.
When running the Windows 7 VM in Parallels v10 (both restored from the Air), I can no longer connect to bluetooth devices.
I have uninstalled all Apple Bluetooth drivers from Windows and then followed the instructions in article 117550 to download and install these drivers.
Bluetooth still does not work.

 

Hi Anne
Just to make sure: you have bluetooth checked under Actions-Configure-Hardware -USB & Bluetooth-Check Bluetooth on left hand side.
I would update Parallels Tools.

Hi Kat.
Yes I have "Bluetooth devices" checked and I have re-installed Parallel Tools and uninstalled/re-installed the Apple Bluetooth, Bluetooth Enabler, and Broadcom Bluetooth drivers, but no success.
Oddly enough, when I connected a Bluetooth USB dongle (ASUS), it just worked!
Is there a possibility that Parallels and/or Windows cannot find a driver for the bluetooth device in the brand new MacBook Pro?
