40MB/s 정도 나와서 설마했는데.. 무늬만 3.0이었나?
서로 다른 포트에 연결해봤는데 링크 자체가 480M로 뜬다.

동일 모델, 2021.06 제조품을 연결하니 5000M USB3.0...
칩셋도 바뀌었구만?

혹시 모르니.. RXNP / TXNP를 다시 땜질 해줘봐야 하나?
칩셋은 RTL8154. 8153과 보다 뒷 버전이라 더 좋을 줄 알았는데 8153은 USB3.0 8154는 USB2.0 모델이다.

라벨은 아래와 같이 다른데 인증번호가 같냐. 칩셋 바뀌면 새로 인증 받아야 하는거 아니었나? 그 와중에 칩셋도 바꾸다니 드럽네?
