I have a Logitech Bluetooth Mouse M557. It works with my Ubuntu but I need to re-enable it every time I restart my laptop and reach to desktop. Also it doesn't work on Login screen.

hcitool scan  # it will find MAC of the mouse
sudo bluez-simple-agent hci0 <MAC>
sudo bluez-test-device trusted <MAC> yes
sudo bluez-test-input connect <MAC>

    I have the exact same issue (right down to the same type of mouse) and hcitool scan doesn't pick anything up. Any alternatives? Cheers! – Tamsyn Michael Oct 27 '14 at 9:38
  • For this to work you have to remove your mouse from the bluetooth list (if it's already connected) and make it discoverable. – user398485 Apr 16 '15 at 0:16

Problem is with Bluez. Same issue exists on Debian 7.8 (bluez package 4.99-2). On Debian 8.0 RC1 (bluez package 5.23-2) it works, however still some warning shown for mouse:

[   43.710930] Bluetooth: HIDP (Human Interface Emulation) ver 1.2
[   43.710940] Bluetooth: HIDP socket layer initialized
[   43.852388] hid-generic 0005:046D:B010.0001: unknown main item tag 0x0

So solution would be to upgrade Bluez and other dependencies.
