Repro Steps

I have WSL and want to manage bluetooth from within it.

I've followed this instruction to build the custom WSL, including all the required checks into .config file.

Here's the latest .config file content that built the latest WSL firmware: https://pastebin.com/5CBrBf7c

And have used usbipd to share and attach the bluetooth device through:

usbipd bind --busid={BUSID}
usbipd attach --wsl --busid={BUSID}

Where both run successfully, and:

usbipd list gives:

Connected:
BUSID  VID:PID    DEVICE                                                        STATE
1-9    0e8d:0608  RZ608 Bluetooth(R) Adapter                                    Attached
1-10   0b05:1939  AURA LED Controller, USB Input Device                         Not shared
2-3    045e:07a5  USB Input Device                                              Not shared
2-4    045e:0745  Microsoft Hardware USB Keyboard, USB Input Device             Not shared

Running bluetoothctl scan on result in No default controller available.

My finding concludes that btmtk module is missing within the system. And I don't know how to find/have/run it.

Expected Behavior

To successfully find and manage / interact with bluetooth device.

Actual Behavior

systemctl status bluetooth:

Note I've followed [this procedure (#3)][2] to include `BT_RAM_CODE_MT7961_1_2_hdr.bin` and other files, adding all files.

Therefore:
