The Ultimate Guide to the UGREEN Bluetooth 5.0 USB Adapter (CM390): Drivers, Installation, and Troubleshooting

In an era where wireless peripherals are dominating the market—from noise-canceling headphones to precision gaming mice—having reliable Bluetooth connectivity on your desktop PC or older laptop is no longer a luxury; it’s a necessity. Unfortunately, many desktop computers lack built-in Bluetooth, and older laptops often ship with outdated Bluetooth 4.0 or 4.2 hardware.

  1. Do not plug the adapter in yet.
  2. Run the driver installer as Administrator.
  3. After the installer finishes, restart the PC.
  4. Now plug in the UGREEN CM390.
  5. Windows will detect new hardware. If it asks for a driver location, point it to C:\Program Files (x86)\Realtek\Bluetooth or wherever the installer extracted the INF files.
  6. Restart again.
  7. Note on Windows 7: You may need the Windows 7 Platform Update (KB3020369 and KB3125574) for Bluetooth stack compatibility. Without this, the adapter may fail to pair.
