When I try to activate usb on my laptop, I can't see my device. I see the message below when I request the status of bluetooth.

 bluetooth.service - Bluetooth service


Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)
Active: inactive (dead)

How can I activate it?

    What is YOUR LAPTOP? Which Ubuntu version is installed? Please add output of lspci -knn | grep Net -A2; lsusb to your question.

To check the status of your Bluetooth, use:

sudo systemctl status bluetooth.service

Then consider two possible solutions:

  1. Enable bluetooth via systemctl:

    sudo systemctl enable bluetooth.service
    
  2. Check if your bluetooth is blacklisted:

    1. sudo vi /etc/modprobe.d/blacklist.conf

    2. If the file has blacklist btusb, exit out of the file and run :

      sudo modprobe btusb
      

This should enable Bluetooth.

Since your Bluetooth is dead, the second solution is likely to help you.

  • modprobe ... was the missing link for me, even if not blacklsted, at least in /etc/modprobe.d/blacklist.conf. Apr 24, 2022 at 21:19

Use systemctl to start the Bluetooth service

systemctl start bluetooth
