iMX8QM Android Automotive OS 12 TP-Link UB500 Bluetooth Dongle Issue

[cbl]

Hello,

I want to use TP-Link UB500 Bluetooth Dongle with iMX8QM EVK.

With Embedded Linux Kernel 6.1.1 prebuild image and
I was able to use my Bluetooth Dongle with Embedded Linux Kernel 5.15.32.

But I want to use my Bluetooth dongle with Android Automotive OS 12.

For this I followed the steps below.

1) The parameter "CONFIG_BT_HCIBTUSB=m" is set in the file "imx_v8_android_car_defconfig".

2) Android image was recompiled and flashed to the board.

3) A folder named "rtl_bt" has been created in the "/vendor/firmware" directory within the Image. In this folder "rtl8761bu_fw.bin"
The firmware has been discarded. Board rebooted.

These applied steps were also applied in Embedded Linux and the BLuetooth dongle worked in Linux.

But after following the steps I was not able to get my Bluetooth dongle working on Android Automotive OS 12.

Can you help me with this?

Best regards.
