If you need a specific driver file (e.g., .inf for Windows, .ko for Linux, or firmware .bin), please clarify the exact product name (e.g., “UGREEN BR21 adapter”) and your operating system.

Toggle Modes: If the device has a physical button, holding it while plugging it in may switch it from "Storage" mode to "Bluetooth/Audio" mode. If it connects via USB and Windows doesn't recognize it:
Manufacturer Website: Look for the specific brand of your hardware (e.g., Borofone, Teclast, or generic "Bluetooth 5.0") rather than searching for "Jieli," as Jieli is only the chip maker.
