BIOS에서 Thunderbolt 포트에 대한 보안이 비활성화되었습니다. 문제에는 변화가 없습니다.

bcdDevicePastebin 출력의 USB 루트 허브 값은 커널 버전이 4.17.*임을 나타냅니다.
Pastebin 출력의 마지막 줄은 다음을 나타냅니다.USB 빌보드 장치감지되고 있습니다.
제가 올바르게 이해했다면 이는 장치에 하나 이상의 USB Type-C 대체 모드(DisplayPort 또는 실제로 Thunderbolt일 수 있음)가 있고 시스템이 이를 활성화할 수 없음을 나타냅니다.
커널에 USB Type-C 포트 관리자가 있어야 합니다. 이는 커널 버전 4.17의 새로운 기능 중 하나입니다. 적어도 커널 버전 4.17 이전에는 이라는 이름의 커널 모듈이 있었고 Mac 및/또는 기타 비PC 하드웨어용 다른 모듈 typec도 있었습니다. Type-C 포트 관리가 커널 4.17 이상에서 어떻게 작동하는지 잘 모르겠지만 이러한 모듈이 커널 버전에 있으면 로드해 보아야 할 것입니다.typec_ucsiucsi_acpiucsi_<something>
USB Type-C 지원에 대해서는 아직 많은 작업이 진행 중이며 다음 주요 버전(4.18)에는 Type-C 지원에 대한 자세한 내용이 포함될 것으로 생각됩니다.
xrandr변환기가 본질적으로 DisplayPort-VGA 변환기인 경우 DisplayPort 대체 모드가 성공적으로 활성화되면 명령에 대해 나열된 출력 중 하나로 나타날 수 있습니다. 그러나 이것이 진정한 Thunderbolt 장치라면 기본적으로 시스템을 위한 추가 GPU입니다. lspci추가 그래픽 카드처럼 보입니다.
이 파일Type-C 모드 제어가 작동하는 방식을 설명합니다.
/sys/class/typec/port<number>/<alternate mode>/mode<number>/active기본적으로 어댑터에 해당하는 비슷한 이름의 파일을 찾은 다음 다음과 같은 작업을 수행해야 하는 것 같습니다 (이상적으로는 장치가 감지되면 자동으로).
echo 1 > /sys/class/typec/port<number>/<alternate mode>/mode<number>/active
디렉터리가 비어 있으면 /sys/class/typecUSB Type-C 지원의 모든 부분이 아직 실행되지 않은 것입니다. 이는 Thunderbolt 3 전제 조건입니다.
