I just upgraded to Ubuntu 14.04 and the Bluetooth mouse does not work. I put in new batteries and search for bluetooth devices in Systems Setting; it constantly comes for a moment and then disappears. Mouse light flashes for few seconds on when it's turned on, but then it goes off. Restarted several times.
"hctool scan" finds nothing. "hcitool dev" finds something, but the address is different from what comes for a second when I search for bluetooth in systems setting. I set AutoconnectTimeout=0 in /etc/bluetooth/main.conf, nothing happened.
I am not sure if this a bug in 14.04. Please help if you have any idea.
