@Pat: One important thing: Don't use hciconfig up <dev> anymore. Even if its still there and works to some degree that will only initialize the controller partly as its using an old kernel API. Use bluetoothctl only to power on/off bluetooth:
$ bluetoothctl
[bluetooth]# power on
Changing power on succeeded
As in this case you don't see an LE device this comes from the fact that we power on bluetooth via hciconfig.
