Hey Harry,
Recently I got a Microsoft Designer Mouse which supports bluetooth 4.0 but it doesn't work on Ubuntu 15.04 with bluez4-4.101-0ubuntu25. Although I can pair with it, I can't connect with it. I've noticed that the Class value read in relevant DeviceFound message is 0 (full message in the bottom), and to my surprise there is no "org.bluez.Input" interface exposed on relevant object created after pairing therefore I can't invoke the Connect() method on such interface.
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.
