[x86-64] No Bluetooth device found

    As per the title, Libre isn't seeing my bluetooth headphones when they're in pairing mode. Have confirmed they're going into pairing mode via other devices. Bluetooth is enabled under services. Install is on an old desktop.

    lsusb gives the following:

    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. Hub
    Bus 001 Device 003: ID 2c4e:0115 Mercucys INC MERCUSYS Bluetooth Adapter
    Bus 001 Device 004: ID 1b88:1b01 ShenMing Electron (Dong Guan) Co., Ltd. 2.4G Receiver
    Bus 001 Device 005: ID 0b05:19af ASUSTek Computer, Inc. AURA LED Controller
    Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
    Bus 002 Device 002: ID 04db:3000 Hypertec Pty, Ltd USB DISK Pro
    Bus 002 Device 003: ID 05e3:0626 Genesys Logic, Inc. Hub

    So the bluetooth adapter is being seen.

    Output of dmesg: https://paste.libreelec.tv/skilled-ox.log

    The listing of the device in "lsusb" only proves the USB bluetooth receiver is connected, not that it works or is working.

    To eliminate the LE settings add-on from the process (not known to have issues, but not impossible) you can use "bluetoothctl" to scan for devices and pair them from the console. See how that goes.

    Have just tried bluetoothctl. When putting it into discoverable mode and turning scan on, I get the following:

    hci0 type 7 discovering on
    hci0 type 7 discovering off
    hci0 type 7 discovering on
    hci0 type 7 discovering off
    hci0 type 7 discovering on
    hci0 type 7 discovering off
    hci0 type 7 discovering on
    hci0 type 7 discovering off
    hci0 type 7 discovering on


    Suggests to me that something is going funky?
