After running smoothly since last distro upgrade I suddenly lost my ability to connect to my bluetooth hub (Logitech). After I remotly tried to shutdown the computer which failed i got back home after a couple of days and when rebooting the desktop I could no longer connect to my bluetooth hub. I have no bluetooth icon in the top bar. When starting the bluetooth settings it says no adpater present and i can't swich it on or off.

Info:

Information supplied gotten from this question (http://ubuntuforums.org/showthread.php?t=2143716) Bluetooth works under win7 which I dual boot. I haven't checked if it's turned off in bios due to this.

$ rfkill list 

returns nothing. $ rfkill list all returns nothing.

What I have tried:

  1. Rebooting *100
  2. $ sudo service bluetooth restart
  3. $ sudo /etc/init.d/networking restart and $ sudo /etc/init.d/bluetooth restart
  4. $ sudo apt-get install bluetooth blueman bluez-hcidump bluewho python-bluez bluez-tools
  5. Running live usb of 13.04.
  6. Running live usb of 12.04. When I try to run 12.04 LTS, I can at the start connect my keyboard, however after a few seconds a message about wifi flashes quickly in the notification area and the system craches. If it recovers I am back to the previous state with no bluetooth connection ability. This indicates to me that something can be done about this issue.

Any help would be good
