Loupedeck USB 장치 "libvirtd"가 UDEV 규칙을 통해 Win에 전달되었습니다.

2024-8-22 • tag-icon

나는 가지고있다이 콘솔QEMU에서 실행되는 Win11에 USB로 전달하려고합니다. USB 장치로 "리디렉션"되는 것이 마음에 들지 않았기 때문에 이에 대한 UDEV 규칙을 작성했습니다. b/c 나는 그것을 가지고 있지 않았고 물론 권한도 없었습니다.

규칙:

$udevadm info --attribute-walk --path=$(udevadm info --query=path --name=/dev/ttyACM0)

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

가상 머신이 시작되지만 Loupedeck 장치가 시스템에 언급되지 않습니다. 전혀 찾을 수 없었습니다.

내 단계를 확인하기 위해 USB 펜 드라이브에 대해 매우 유사한 UDEV 규칙을 만들고 이를 성공적인 호스트 장치로 설치했습니다.

그래서 내 질문은: win11 VM에서 이 장치를 사용하기 위해 뭔가 빠진 것이 있습니까? 내가 뭐 잘못 했어요? 창문에서 볼 수 있게 하려면 어떻게 해야 하나요?
