However, the Microsoft Generic Driver often dates back to 2006 and is not optimized for the specific hardware ID (USB\VID_10D7&PID_B012) of the UGreen adapter. If you only use the generic driver, you are essentially running the adapter in a "compatibility mode." You lose access to the advanced features of Bluetooth 5.3, such as higher data throughput, improved Low Energy (LE) Audio, and better interference management. To achieve the full advertised speed and stability of Bluetooth 5.3, installing the manufacturer-specific driver is essential.
