PS3 sixaxis BT 4.0 vs 2.0

[andrea <mariofutire@gmail.com>]

Hi,

I would like to know if there is any chance of running a PS3 sixaxis controller with a BT dongle 2.0

I know it works well with BT 4.0 and bluez 5.18.
My hope that it works with a dongle 2.0 is because when I used to run sixad (before bluez 5.xx) it
worked well.

I've logged some data with 2 dongles hoping some of you guys can find what the difference is.
Basically the controller is paired well in both cases, it gets connected and creates a
/dev/input/js0 device.

The problem with 2.0 is that /dev/input/js0 does not produce much data. Just a few lines at the
begin and then nothing else. With 4.0 whenever I touch the buttons, more data is read from it.

I've logged data with

hcidump -X -w /tmp/b2.0.txt
and then processed it with
btmon -r b2.0.txt > b2.0.out.txt

I've uploaded the 4 files here
