華碩主機板（PRIME B550M-A (WI-FI)）規格有提到【藍牙】。

華碩也提供【藍牙】驅動程式。
版本 21.70.0.3

我安裝時，它迅速灌完。其安裝速度遠快於安裝其他驅動程式，仿佛我主機板沒藍牙。
然而，我從win10裝置管理員或PCInfo軟體去查，都沒發現自己主機板上有【藍牙】裝置。
我用win10内建功能去找藍牙，但系統顯示【藍牙在裝置上不可用，請嘗試用外部配接器向該電腦提供藍牙功能。】
我進BIOS查詢后，BIOS顯示我已經開啓【藍牙控制器】了。
請問，我該如何處理？謝謝。
PS:
我的作業系統：Win10 20H2（OS組建：19042.789）
我改用Manjaro Linux、Linux Mint也找不到自己主機板上的【藍牙】裝置。
我的主機板、網路裝置清單如下。
