Bluetooth adapters are not recognized

General system Kernel, boot, graphics & hardware

Hi. After today update I have got two problem.

❯ uname -a
Linux stey 6.6.51-1-lts #1 SMP PREEMPT_DYNAMIC Thu, 12 Sep 2024 11:23:10 +0000 x86_64 GNU/Linux

  1. On boot and getting SDDM welcome screen both keyboard and mouse don’t work (of course, the do in BIOS). To “resolve” the problem I need to remove Bluetooth USB adapter on booting (yes, it is very strang magic, but I have tried fiew times, and it doesn’t depend on concrete adapter, I have got few different of them).

  2. After booting wityout BT adapter and inserting it after entering a system (KDE) I don’t get bluetooth. Fragment of dmesg:

[ 8321.677794] usb 1-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 8321.677796] usb 1-1.4: Product: TP-Link UB500 Adapter
[ 8321.677798] usb 1-1.4: Manufacturer:  
[ 8321.677799] usb 1-1.4: SerialNumber: E848B8C82000

And from systemd status:

○ bluetooth.service - Bluetooth service
     Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; preset: disabled)
     Active: inactive (dead)
       Docs: man:bluetoothd(8)

Please, any ideas?

Are you able to try booting with the standard kernel and see if the issue remains consistent?

Yes, and keyboard with mouse lock on SDDM regardless adapter presence.

Nothing changes.

Probably it is another sign of the problem: on KDE session logout (or shutdown) I get black screen with mouse cursor. So I am forced to Ctrl-Alt-Fn to go to termianl and restart sddm (or use poweroff to shutdown.). X11 is in use.

Ok, magic has gone. There were a problem (probably introduced by mine) with kernel update. I have resolved it (in fact reinstalled kernels and few eos packages), and everything does work.
