I tried with this and your earlier DS4 patch, on top of a Fedora 20 Live
CD, and unfortunately it does not work for me. I still get the situation
where the DS initiates a connection and then turns off immediately.

I get the log messages
--
Jan 19 14:01:14 localhost systemd: Reached target Bluetooth.
Jan 19 14:01:14 localhost bluetoothd[1803]: Refusing input device connect:
No such file or directory (2)
Jan 19 14:01:14 localhost bluetoothd[1803]: Refusing connection from
1C:66:6D:07:C3:E0: unknown device
--

See log files:
pair_ds4_fedora.txt
connect_ds4_fedora.txt

There is also a problem when the pairing is initiated from the PC side,
seems that the resultant link key is not accepted on connection.

See:
pair_fedora_ds4_2.txt
connect_ds4_fedora_2.txt

I note that the cache file for the DS4's mac picks up some details on a
SDP browse, but not a complete record. This is on an older machine, so BT
chipset might be a factor.

Anything I can try?
Simon
