# Linux Mint 22.3 Cinnamon

This guide explains how to use a USB Bluetooth dongle on Linux Mint when the computer does not have built-in Bluetooth, the internal Bluetooth adapter is not working properly, or you are using a desktop PC.

### 1. Insert the Bluetooth Dongle

Plug the USB Bluetooth dongle into an available USB port on the computer.

It is recommended to connect the dongle directly to the PC rather than through a USB hub.

{% hint style="info" %}
Note: In many cases, Linux Mint automatically detects the USB Bluetooth dongle and shows it in the Bluetooth settings menu immediately after it is connected. If the dongle appears automatically and works correctly, running Terminal commands is not required. Commands such as `lsusb`, `hciconfig`, and `bluetoothctl` are only needed for troubleshooting if the dongle is not detected or does not work properly.
{% endhint %}

### 2. Check Whether Linux Detects the Dongle

Open Terminal and run:

```bash
lsusb
```

You should see your Bluetooth dongle listed among the USB devices.

### 3. Check Whether the Bluetooth Adapter Is Available

Run:

```bash
hciconfig
```

### 4. Open Bluetooth Settings

Open the application menu and go to:

Settings → Bluetooth

Make sure Bluetooth is enabled.

Your USB dongle should appear as the active Bluetooth adapter.

### 5. Pair a Device

Turn on Bluetooth on the device you want to connect, such as:

* phone
* headset
* speaker
* mouse
* keyboard

In Bluetooth settings:

1. Click Search or Scan.

3. Click Pair.
4. Confirm the pairing code if required.

### 6. Pair Devices Through Terminal (Optional)

To pair a device through Terminal:

```bash
bluetoothctl
```

Then run:

```bash
power on
agent on
default-agent
scan on
```

Wait until your device appears.

Then use:

```bash
pair XX:XX:XX:XX:XX:XX
connect XX:XX:XX:XX:XX:XX
trust XX:XX:XX:XX:XX:XX
```

Replace `XX:XX:XX:XX:XX:XX` with the Bluetooth MAC address of your device.
