Sorry, I do not know what software versions changed updating to openSUSE 
Tumbleweed. Could you please mention that for the Linux kernel and BlueZ 
and the initrd generator?

 From Qu’s answer in the thread *[PATCH v3 1/2] Bluetooth: btusb: Add

was only added recently, and is going to be in Linux v6.6.


Kind regards,

Paul
