Fedora 34를 실행하는 노트북에서 연결된 USB UVC 카메라가 감지되지만 키보드로 인식됩니다.
cheese이 카메라는 입력 장치로 간주되지 않으며 내장 웹캠으로만 간주됩니다.
카메라를 올바르게 감지하려면 어떻게 해야 합니까?

답변1
나는 같은 오류가 있었고 X11 구성에 몇 가지 무시를 추가했습니다.
먼저 command 를 사용하여 cam이 키보드로 나열되어 있는지 확인한 다음 (또는 확장자가 conf인 파일 이름) xinput list이라는 파일을 만듭니다./etc/X11/xorg.conf.d/00-fix-cam.conf
내부에 다음 줄을 추가하세요.
Section "InputClass"
Identifier "none"
MatchVendor "Chicony USB2.0 Camera: Chicony"
Option "Ignore" "true"
EndSection
Section "InputClass"
Identifier "none"
MatchProduct "Chicony USB2.0 Camera: Chicony"
Option "Ignore" "true"
EndSection
올바른 공급업체 및 제품 이름을 얻으려면 명령을 사용하고 lsub -vv그에 따라 값을 바꾸십시오(또는 명령이나 명령을 더 잘 사용하십시오).MatchVendorMatchProducthwinfo --usbudevadm info -a /dev/input/by-id/*
식별자가 작동하지 않으면 식별자 를
none사용해 보십시오system-keyboard.keyboardlibinputcatchall
일부 이름 끝에 추가 공백이 포함되어 있습니다. 무시 구성에 추가해 보세요.
X 세션을 다시 시작하고 명령을 실행하여 xinput list카메라가 이제 키보드 입력에서 제외되는지 확인합니다.
중요한:새 구성으로 인해 X 세션이 중단되고 콘솔 액세스가 손실될 경우 SSH를 활성화하고 다른 시스템에서 원격으로 연결해 보십시오.
노트:또한 카메라가 활성화되어 있는지 확인하세요(일부 카메라에는 활성화 및 비활성화할 수 있는 물리적 버튼이나 키보드 단축키가 있음).
답변2
음, 원칙적으로는 웹캠으로 인식됩니다.
kernel: uvcvideo: Found UVC 1.00 device DP 5M CAM (2b16:6689)
이것은반품카메라에 "스냅샷" 키가 있으면 키보드로 인식되는 것은 놀라운 일이 아닙니다. 내 카메라에서도 같은 일이 일어납니다.
그렇다면 질문은 초기 식별을 넘어 왜 찾을 수 없는가 uvcvideo입니다 . cheese올려주신 발췌글 아래에 UVC나 영상장비 관련 소식이 있나요? 어쩌면 오류 메시지일까요?
몇 개의 장치가 보이나요 ls /dev/video*? lsusb -vv카메라를 위해 뭔가 특별한 일을 한다면 어떨까요 ?
