어떤 포트에 문제가 있는지 어떻게 알 수 있나요?
답변1
이 메시지는 USB 버스 4의 USB 허브 포트 4와 관련이 있습니다. 포트를 활성화할 수 없으므로 포트에 연결된 모든 장치는습관에서 볼 수 있습니다 lsusb.
따라서 USB 장치의 목록을 작성하여 USB 장치가 있는지 확인해야 합니다.목록에 없음lsusb출력 에서 . 이곳은 테스트를 시작하기에 좋은 장소입니다.
오류 메시지에 USB 버스 4가 언급되어 있고 해당 버스에는 루트 허브( ) 이외의 허브가 없으므로 Bus 004 Device 001문제를 보고하는 포트는 일부 외부 USB 허브가 아닌 실제 컴퓨터에 있는 것으로 보입니다. 물론, Thunderbolt 연결 도크와 같은 장치가 있는 경우 USB 하위 시스템에 관한 한 "실제 컴퓨터"의 일부로 간주되는 추가 USB 버스를 제공할 수 있습니다.
그럼에도 불구하고 2개 이상의 WD My Book 25EE 휴대용 하드 드라이브가 연결된 부품을 찾은 다음 USB를 통해 해당 부품에 연결된 다른 장치가 있는지 확인하십시오.
USB 장치가 상당히 많기 때문에 트리 형식의 목록에 허브 포트 번호가 포함되어 있으므로 lsusb --tree이것이 일반적인 것보다 더 유용할 수 있습니다 .lsusb
Bus 04그러나 오류는 허브 포트에서 보고되므로 포트 수준에서 문제가 감지 되므로 어떤 장치도 표시되는 것을 원하지 않습니다 Port 4. USB 케이블이 단락되어 장치와의 통신이 차단될 수 있습니다. 해당 케이블의 다른 쪽 끝. 트리 구조의 동일한 "분기"에 있는 다른 장치를 확인하여 포트를 식별해야 합니다.
