Hi community, 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. Furthermore, after pairing its object path is contained in the Devices property of local adapter, but the linkkeys file contains no relevant entry. Home come bluez reads class value 0 from this device? does this attribute to no input interface exported by bluez? how can I better attack this problem? Many thanks for any advice.
