시스템이 USB 3.0 포트를 USB 2.0 포트로 인식합니다.

저는 USB 3.0 포트(파란색, 표시됨 SS)가 있는 Lenovo 4338-35 도킹 스테이션을 갖춘 Thinkpad T520 노트북을 가지고 있습니다. 그러나 내 Linux Mint 17.2에서는 이를 인식하지 못합니다.

이 포트에 연결된 장치는 다른(USB 2.0) 포트와 마찬가지로 작동합니다.

USB 3.0 장치가 나타나야 하는 속도를 보여주는 다른 사람들의 출력 결과를 본 적이 있지만 5000M저는 480M.

USB 3.0으로 인식되는 방법에 대한 단서를 제공할 수 있는 사람이 있습니까? 감사해요.

답변1

하드웨어 문제라 커널 문제인지는 잘 모르겠습니다... ThinkPad T520 사양을 온라인으로 확인해보니 마더보드에 USB 3.0 기능이 전혀 없습니다. 3.0 포트를 사용하는 경우 노트북의 포트로 인해 병목 현상이 발생합니다. 이것은PDF내가 찾은 420/520 시리즈 노트북의 기술사양메세지 보드Lenovo 포럼에는 더 유용한 링크/정보가 있습니다.
