[Bug 1433987] Re: [Realtek 0bda:b728] Bluetooth is useless after installed 14.04.2


The device works here, but I get:

lappy2 kernel: [340105.430341] Bluetooth: hci0 ACL packet for unknown
connection x (where x is one of 1 to 12)

And it takes a couple of minutes of clicking on the mouse until I get
some response on the screen. I'm running Wily at the moment (kernel
4.2.0-11). When the mouse or the device goes to sleep kernel loses the
connection and then notices that something is sending packages but it
won't do anything about it.
