我正在尝试让这个旧网络摄像头与 Ubuntu 配合使用。Cheese 显示“未找到设备”。Zoom 应用程序仅将“摄像头”显示为视频设备，但没有图片。Camorama 程序能够获取图片，所以我不确定为什么 3 个程序中有 2 个不起作用。lsusb 显示：总线 005 设备 002：ID 046d:092d Logitech, Inc. QuickCam Express / Go
如果我拔下并重新插入，dmesg 会显示：
[10381.658660] usb 5-1: USB disconnect, device number 2

[10384.435577] input: spca561 as /devices/pci0000:00/0000:00:1a.2/usb5/5-1/input/input15
该设备显示在/dev 中：
/dev/video0 -l
crw-rw----+ 1 root video 81, 0 Mar 29 05:31 /dev/video0
我以为是权限问题，但我以“john”身份登录，并收到以下信息：cat /etc/group|grep vid video:x:44:john 因此我的用户代码在视频组中。如果我从命令行运行 cheese，则会收到以下错误：
