Ich habe Ubuntu 22.04 installiert und irgendwann funktionierte mein Bluetooth nicht mehr.
Ich habe einen externen Bluetooth-Dongle: Amitosai MTS-BT5PRO. Ich denke, das Problem könnte bei diesem Gerät liegen, aber es ist seltsam, dass es unter Ubuntu 20.04 einwandfrei funktioniert hat.
Der Dienst ist (theoretisch) aktiv, kann jedoch keine neuen Geräte erkennen und keine Verbindung zu bereits gekoppelten Geräten herstellen.
Beweisen Sie, dass das Gerät erkannt wird (Realtek Semiconductor Corp. Bluetooth Radio):

Der Dienst scheint zu laufen (wie im Bild gezeigt)
aber die Protokolle werfen zwei Fehler aus:

Weißt Du, wo der Fehler liegen könnte?
Wenn Sie glauben, dass es am Dongle selbst liegt, könnten Sie mir einen empfehlen, der mit Ubuntu 22.04 kompatibel ist?
