To enable full bluetooth functionality, you have to edit
/System/Library/Extensions/IOBluetoothFamily.kext/Contents/PlugIns/BroadcomUSBBluetoothHCIController.kext/Contents/Info.plist
Search the section that starts with
<key>Broadcom2046FamilyUSBBluetoothHCIController</key>
Be sure to edit the 2046 section and not 2045!
Search the lines
<key>idProduct</key> <integer>8262</integer> <key>idVendor</key> <integer>2652</integer>
and replace it with
<key>idProduct</key> <integer>46848</integer> <key>idVendor</key> <integer>2821</integer>
Save the file, repair permissions, delete Extensions.mkext and reboot.
I would have added my modified kext but I could not find any options to attach files to my post…
