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.
