The problem here seems to be that the mouse doesn't support HID but HOGP
(see [1]). BlueZ 4.x doesn't support HOGP. Ubuntu 15.10 already has
BlueZ 5.35 which has all needed things to support HOGP but I don't know
for sure if it already works today. Someone else can give you more
details here but you should definetely update to Ubuntu 15.10 to get the
newer required BlueZ version.
regards,
Simon
