I currently have a problem when pairing my computer with a PS4 remote. On my Ubuntu 14.04 I removed everything related with bluez and bluetooth, and I built and installed bluez 5.19.

Here are some useful command outputs:

jean@system ~ hcitool   
hcitool - HCI Tool ver 5.19

jean@system ~ hcitool dev
Devices:
    hci0    00:15:83:4C:0C:BB

jean@system ~ bluetoothctl 
[bluetooth]# version
Version 5.19

jean@system ~ bluetoothctl 
[NEW] Controller 00:15:83:4C:0C:BB BlueZ [default]

jean@system ~ lsusb
Bus 003 Device 012: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

So here is what happens. When I try to hard pair the controller with the computer, by holding the share and ps button for a while, everything works as expected and the pairing is done properly. After a hard pairing if I try the pairing by pressing the ps button only, nothings happen. In order to go it, I first power up the bluetooth dongle:

jean@system ~ sudo hciconfig hciX up

and then I run the bluetooh deamon bluetoothd:

jean@system /usr/libexec/bluetooth ~ ./bluetoothd -d -n

And then I press the ps button of the PS4 controller

So I don't know what is happening here and a bit of help would be appreciated.
