When I installed Fedora 20 fresh on a Dell Latitude E6440, I was unable to use bluetooth. The gnome control panel for bluetooth says no adapters are found.
discovering state
- the spec sheet for a Dell Latitude E6440 says:
Connect and collaborate effectively with Dell docking solutions, Bluetooth® 4.0, integrated HD webcam and mobile broadband options.
- dmesg says this at boot:

Found this config file:
/etc/dbus-1/system.d/bluetooth.conf
- Ahh, my system bios says this
Doh. I need to buy a bluetooth adapter.
- Dell's factory install configuration link was less helpful

It seems like it would be a good idea to check Dell's records to see what they installed, but the parts list is incomprensible.
