I am having HP Probook Laptop. Since I have installed ubuntu 14.04 LTS, my laptop is not connecting with any device using bluetooth. Other device is also not detecting my laptop. I have no option to boot windows on my laptop as I use ubuntu 14.04 LTS only. I have tried many solutions provided on different online forums. But those are not helpful for me. I am having hardware and drivers setting properly. Still the problem persists. The issues is haunting me since long. Please help me to solve this problem. Regards

These are the outputs of the command suggested.

  • @pilot6 I'm on my phone so can't test 'kspci" but do you mean 'lspci'? Sep 14, 2016 at 17:24
  • It is a typo lspci -knn | grep Net -A2; lsusb

It looks like you never updated your system. You have an ancient kernel that doesn't have support of the device. The support has been added by this commit

Run in a terminal

sudo apt-get update
sudo apt-get upgrade

You should get the 3.13.0-126 kernel that has support of this device.

  • Whether running the command mentioned above automatically will update the kernel or I have to do something in addition

  • It is all you need. It will update the system. You need to reboot after it finishes.
