Missing Bluetooth device drivers?

[4-FLOSS-Free-Libre-Open-Source-Software]

Kernel missing Bluetooth device drivers to turn on Bluetooth USB adapter device.
CONFIG_BT_RTL=y: Bluetooth device drivers

zcat /proc/config.gz | grep CONFIG_BT_RTL
zcat /proc/config.gz | grep CONFIG_BT_HCIBTUSB
# CONFIG_BT_HCIBTUSB is not set
zcat /proc/config.gz | grep CONFIG_RFKILL
# CONFIG_RFKILL is not set

RFKILL may be required to power on the chip

rfkill list
rfkill: /dev/rfkill not found...

• Enable Bluetooth support #82

This other custom WSL kernel seems to have Bluetooth support: https://github.com/dathpo/wsl2-linux-kernel?tab=readme-ov-file#readme-fork
