Bluetooth v5を設定する方法

Bluetooth 5 USB doogleを起動しようとしています（MPOW BH456A）。 Mpowウェブサイトから最新バージョンのLinuxドライバをダウンロードしてください sudo make install INTERFACE=all。次のエラーが原因でこの操作は失敗します。

私はKDEバージョンのFedora 32を使用しています。

以下は、私がフォローしようとしていたBluetoothドライバを手動でインストールするためのMPOWの説明です。

-Installation

  1. Build and install USB driver, change to the driver directory
   $ cd usb
   $ sudo make install

  2. Copy the right FW file and config file to the correct path.
   $ sudo cp rtkbt-firmware/lib/firmware/rtl8xxxxx_fw /lib/firmware/
   $ sudo cp rtkbt-firmware/lib/firmware/rtl8xxxxx_config /lib/firmware/

   NOTE: PLEASE REFER THE FORWARD SECTION OF FILENAME LIST TO CORRESPOND THE FW FILENAME AND THE CONFIG FILENAME WITH THE CHIP.
           
  3. Insert Realtek Bluetooth dongle
    Check LMP subversion by the following command
    $ hciconfig -a

    Now RTK chip can be recognized by the system and bluetooth function can be used.
