I wasn't right, the mouse seems to support autopairing and I paired it
without problem under RHEL-7 and it also works there without problem.
I tried to shuffle user-space bluez and there is no change, so it has to be
kernel. I also tried with CSR USB dongle. Regarding the sspmode error,
it's probably not supported by the HW. To sum it up:

kernel-3.10.0-229.el7.x86_64 - it works
kernel-4.5.7-200.fc23.x86_64 - it doesn't work

I am going to bisect with vanilla kernel

thanks & regards
