华硕笔记本内置Sonix USB摄像头无法工作的排查及相关疑问咨询

我华硕笔记本的内置摄像头无法正常工作，打开Cheese这类摄像头应用时，会显示“no device found”的提示。

我的内置摄像头信息：
Sonix Technology Co., Ltd. USB2.0 HD UVC WebCam

lsusb命令输出： #

从dmesg输出可以确认，系统已经检测到这款Sonix USB2.0 HD UVC WebCam，负责处理UVC兼容摄像头的uvcvideo驱动也已加载，但存在一条关于UVC不兼容的警告：

我现在有几个疑问，希望能得到解答：

• 如何进一步排查这个摄像头无法工作的问题？
• 是否需要安装额外的驱动或者进行特殊配置才能让摄像头正常工作？
• 这条“UVC non-compliance”警告具体是什么意思，有没有办法解决这个问题？

感谢各位的解答和建议！
