To install the driver of the UGREEN USB Bluetooth 5.0 adapter without using the supplied CD, follow these steps:

## Step 1: Connect the adapter
Plug the Bluetooth adapter into a free USB port on your computer.

## Step 2: Automatic detection
Most modern Windows operating systems (Windows 11, 10, 8.1) recognise the adapter automatically and install the necessary drivers without an additional CD. This process should be completed within a few seconds.

## Step 3: Manual driver installation (if necessary)
If the automatic installation does not work, you can download the drivers directly from the UGREEN website. Visit the official UGREEN website, search for the product with the part number 80889 and download the corresponding drivers.

## Step 4: Install the driver
Run the downloaded driver file and follow the on-screen instructions to complete the installation.

## Step 5: Check the connection
After installation, the Bluetooth adapter should be visible in your system. You can now connect Bluetooth devices such as headsets, mice, keyboards and other devices.

This process is usually simple and does not require any additional CDs or manual intervention, as the drivers are installed automatically in most cases.
