我的华硕笔记本电脑上的集成摄像头无法使用。当我打开 Cheese 等应用程序时，它显示“未找到设备”。

dmesg 输出确认我的 Sonix Technology USB2.0 HD UVC WebCam 已被系统检测到。uvcvideo 驱动程序也已加载，该驱动程序负责处理兼容 UVC 的网络摄像头。但是，有一个关于 UVC 不合规的警告：

我该如何进一步排除此问题？是否需要任何额外的驱动程序或配置才能使相机正常工作？“UVC 不合规”警告是什么意思？我该如何解决？
感谢您的回答和建议
答案1
到目前为止，我已经找到了解决您和我的问题的答案。1- 在 cheese 中使用较低的分辨率。2- 如果第一个解决方案不能解决问题，请从 ubuntu 商店下载 cameractrls 并授予其访问相机的权限，在我的情况下，我必须将自动曝光设置为手动，并将曝光时间减少到 5500 才能使 cheese 正常工作，如果您对结果满意，请不要忘记保存。我现在遇到的唯一问题是 cheese 和我尝试过的其他应用程序中的动作滞后，但那是另一个故事。
