저는 CentOS v.7.5.1804, 커널 3.10.0-862.el7.x86_64를 실행하고 있습니다.
호스트에는 /dev/ttyACM0게스트 가상 머신에 매핑된 USB 동글이 있습니다.
VM이 실행 systemctl suspend되고 복원된 후에 /dev/ttyACM0는 제거되지만 다시 추가되지는 않습니다. 제가 사용할 수 있는 유일한 방법은 동글을 다시 삽입하는 것이었습니다. 아래는 목록입니다 udevadm monitor.
물리적 어댑터를 다시 연결하지 않고도 동글을 감지할 수 있습니까?
현재 문제를 해결하는 것도 도움이 될 것 같아요이것.

답변1
글쎄, 나는 여전히 동글이 다시 나타나지 않는 문제에 대한 해결책을 찾지 못했지만 조사하는 데 진전이 있었고 잘못된 커뮤니티에 질문을 게시했다는 것을 깨달았습니다. 동글은 명시적으로 전달하지 않고도 다시 나타날 수 있습니다. 물리적으로 다시 연결하고 다시 연결하십시오. -호스트의 VMWare Fusion USB 옵션에서 활성화합니다. 따라서 VMWare Fusion은 게스트 CentOS VM이 아닌 복구 동글을 담당합니다.
