Bluetooth detects no devices and vice versa in Ubuntu 16.04 LTS
I am unable to find any device in Bluetooth and my system is not detected by any device while Bluetooth is on. Is there any driver I need to install for Bluetooth?
Edited:
It detects my bluetooth headphone but failed to pair up and it is not detecting any other bluetooth device.
output for lsusb; dmesg | egrep -i 'blue|firm'
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Could you please add a little more detail? What exactly did you do, what did you want to achieve and what happened instead? Did you encounter any warning or error messages? Please reproduce them in their entirety in your question. You can select, copy and paste terminal content and most dialogue messages in Ubuntu. (see How do I ask a good question?)

When opening system settings and clicking on the Bluetooth option, I got the message 'No Bluetooth found'
This what worked for me to fix it (terminal command line):
sudo modprobe -r btusb
sudo modprobe btusb
sudo service bluetooth restart
sudo apt-get install blueman
Then go to Search for files on the computer (), type in blueman (this is the bluetooth manager).
You can then enable bluetooth once it opens up.

Once you install blueman, the System Settings for Bluetooth worked. So, when you type in 'blue' in the Search for files field, you will see two bluetooth icons: the manager and the ones from the system. 1. Open Manager and 'Enable Bluetooth' 2. Open the other icon, from the system settings, and turn on bluetooth; also turn on visibilty. They are two separate sliders to move, on the same screen.

Blueman is a way of managing bluetooth, its unlikely to help set-up the right drivers and firmware that are probably needed in most cases to fix the issue, though with some (often older) OSs it does provide a better interface that may work better

Now, change the line #USB_BLACKLIST="1111:2222 3333:4444" to USB_BLACKLIST="<ID>" (in my case to USB_BLACKLIST="0bda:b721") in /etc/default/tlp.
Reboot and everything should work.

Could you please add a little more detail? What exactly did you do, what did you want to achieve and what happened instead? Did you encounter any warning or error messages? Please reproduce them in their entirety in your question. You can select, copy and paste terminal content and most dialogue messages in Ubuntu. (see How do I ask a good question?)
