![Bluetooth 동글이 감지되었지만 Ubuntu 22.04에서 작동하지 않습니다](https://rvso.com/image/1073515/Bluetooth%20%EB%8F%99%EA%B8%80%EC%9D%B4%20%EA%B0%90%EC%A7%80%EB%90%98%EC%97%88%EC%A7%80%EB%A7%8C%20Ubuntu%2022.04%EC%97%90%EC%84%9C%20%EC%9E%91%EB%8F%99%ED%95%98%EC%A7%80%20%EC%95%8A%EC%8A%B5%EB%8B%88%EB%8B%A4.png)
Ubuntu 22.04를 설치했는데 어느 시점에서 블루투스 작동이 중단되었습니다.
블루투스 외부 동글인 Amitosai MTS-BT5PRO가 있습니다. 이 장치에 문제가 있는 것 같지만 Ubuntu 20.04에서는 제대로 작동하는 것이 이상합니다.
서비스가 이론상 실행 중이지만 새 장치를 감지하거나 이미 페어링된 장치에 연결할 수 없습니다.
장치가 감지되었음을 증명합니다(Realtek Semiconductor Corp. Bluetooth Radio).

서비스를 다시 시작하면 블루투스 오류가 표시됩니다.
그리고 dmesg | grep -i bluetooth
이것을 던졌습니다:

무엇이 오류일 수 있는지 아시나요?
동글 자체라고 생각된다면 Ubuntu 22.04와 호환되는 동글을 추천해주실 수 있나요?
