Ubuntu 22.04 busca interminável por dispositivos, mas nada encontrou bluetooth

Eu sou novo no Ubuntu. Meu Bluetooth faz uma busca interminável por dispositivos, mas nada foi encontrado. A saída de dmesg | egrep -i 'blue|firm' fornece:

Talvez seja esta linha:

    [  648.522053] Bluetooth: hci0: urb 000000007e15b852 failed to resubmit (2)

Como posso consertar isso?

Parece um problema de kernel que acontece se o seu kernel for >= 5.9, você pode usar uname -rpara verificar a versão do seu kernel. Alguns tópicos relacionados:https://bbs.archlinux.org/viewtopic.php?id=259954

Como usuário do MX master 3S e ubuntu22.04, eu uso o logitech bolt receiver esolarpara personalizá-lo por enquanto.

Espero que isso ajude.
