    Bluetooth stopped working suddenly

    I am not able to see `bluetooth` symbol on the `panel`.
    I checked with `Unity Tweak Tool` and there is a tick mark for bluetooth.

    Further, I ran the command
    Code:
    sudo service bluetooth status
    and it gave
    Code:
    bluetooth start/running, process 744
    Code:
        tasdik@Acer:~/Dropbox/code$ rfkill list
        0: acer-wireless: Wireless LAN
                Soft blocked: no
                Hard blocked: no
        1: phy0: Wireless LAN
            Soft blocked: no
            Hard blocked: no
    And

    Code:
    tasdik@Acer:~/Dropbox/code$ sudo bluetoothd -d -n
        bluetoothd[18809]: Bluetooth daemon 4.101
        bluetoothd[18809]: src/main.c:p****_config() parsing main.conf
        bluetoothd[18809]: src/main.c:p****_config() discovto=0
        bluetoothd[18809]: src/main.c:p****_config() pairto=0
        bluetoothd[18809]: src/main.c:p****_config() pageto=8192
        bluetoothd[18809]: src/main.c:p****_config() auto_to=60
        bluetoothd[18809]: src/main.c:p****_config() name=%h-%d
        bluetoothd[18809]: src/main.c:p****_config() class=0x000100
        bluetoothd[18809]: src/main.c:p****_config() Key file does not have key 'DeviceID'
        D-Bus setup failed: Name already in use
        bluetoothd[18809]: Unable to get on D-Bus

    Because of it I am not able to transfer files between my PC and mobile devices.

    Any ideas guys?

    Edit : Tried some more things, gave me these

    Code:
        tasdik@Acer:~$ lsusb
