If you are using an older version of Windows, you will almost certainly need to install a driver manually. These legacy operating systems do not have the native support for Bluetooth 5.3 and its underlying ATS2851 chipset.
However, older kernels (before 5.18) may fail to load the firmware. In that case, the "driver" is actually a manual firmware update via fwupd or copying new .bin files. The community maintains these firmware blobs because Realtek does not open-source them – they are signed blobs executed by the chip's internal microcontroller. driver ugreen bluetooth 53
For models like the CM591 , which uses the ATS2851 chip , manual installation is often necessary. If you are using an older version of
