USB 오디오 장치(Tascam US-2x2HR)가 가끔 로드되지 않아 다른 USB 장치가 작동하지 않게 되는 경우가 있습니다. 이 문제를 해결하거나 디버깅하려면 어떻게 해야 합니까?

Windows와 Ubuntu 22.04.01 LTS를 이중 부팅했습니다. Windows에서는 내 오디오 장치(Tascam US-2x2HR)가 제대로 작동합니다. 우분투에서는 부팅 시 작동하지 않지만 플러그를 뽑았다가 다시 연결하면 결국 완벽하게 작동합니다. 때로는 컴퓨터를 연결할 때 컴퓨터가 부분적으로 멈추는 것처럼 보이지만(예: 버튼을 클릭하여 터미널을 열 수 있음) 오디오 장치를 분리할 때까지 터미널이 열리지 않습니다.

이것은 내가 찾는 방법을 아는 최고의 로그 조각입니다. 물론 추가 정보를 제공하게 되어 기쁩니다!

dmesg다음은 관련 정보가 있는 것으로 보이는 일부 내용입니다 .

장치를 연결했는데 작동하지 않을 때 tail -f /var/log/syslog이런 일이 발생합니다 .

때때로 장치가 표시되고 lsusb(작동하지 않더라도) 때로는 lsusb를 실행하면 장치를 분리할 때까지(또는 오랫동안 기다릴 때까지) 터미널이 정지됩니다.

마지막으로 syslog성공적인 연결 해제/연결 후의 모습은 다음과 같습니다. 그 후 장치는 잘 작동했습니다.
