Can't connect a Xbox one controller

Hi,

I've recently bought a new xbox one controller as the 2016 version has
bluetooth connectivity.

The controller is pairing and connecting well on a windows 10 computer
and an android 4.4 tablet. But I can"t make it connect under linux
(Debian unstable, kernel 4.6 and 4.7-rc7, bluez 5.40 from
experimental). The pairing is ok but when I try to connect to
controller, it stays connected for less than one second, then
disconnects, then connects again and so one until the controller goes
to sleep, because of the lack of a remote connection.

Any idea ?
