Dear Jürgen,

I updated openSuse Tumbleweed 20230806 with a bluetooth keyboard

bluetooth was disabled and it was impossible to enable it again.
Before the update bluetooth was working fine.
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?
The attached bluetooth keyboard caused the bluetooth module being
added to initrd. However, the corresponding firmware for MT7922 is not
added.
dmesg shows:
[ 4.368031] bluetooth hci0: Direct firmware load for
mediatek/BT_RAM_CODE_MT7922_1_1_hdr.bin failed with error -2
In fact the file is present on the system
ls -l /usr/lib/firmware/mediatek/BT_RAM_CODE*
-rw-r--r-- 1 root root 512104 3. Aug 17:36
/usr/lib/firmware/mediatek/BT_RAM_CODE_MT7922_1_1_hdr.bin.xz
-rw-r--r-- 1 root root 343052 3. Aug 17:36
/usr/lib/firmware/mediatek/BT_RAM_CODE_MT7961_1_2_hdr.bin.xz
but missing in initrd
lsinitrd | grep BT_RAM_CODE
-rw-r--r-- 1 root root 343052 Aug 3 17:36
usr/lib/firmware/mediatek/BT_RAM_CODE_MT7961_1_2_hdr.bin.xz
Manually adding the file to initrd makes bluetooth work again.
I reported the bug here
https://bugzilla.suse.com/show_bug.cgi?id=1214133
and was requested to report here.
If I can be of any help or you need further information please let me
know.
From Qu’s answer in the thread *[PATCH v3 1/2] Bluetooth: btusb: Add
new VID/PID 0489/e102 for MT7922* [1] it sounds to me, support for chip
was only added recently, and is going to be in Linux v6.6.
I think this is a different one.
The new pid (0xe102) is only introduced in some recent laptops (with
ryzen 7040 series CPUs I guess?).
Unless the user is compiling a custom kernel with the extra vid/pid
added, it should not work from the very beginning.
Thus I believe it's something different.
Thanks,
Qu
Kind regards,
Paul
