我有一个USB网络摄像头(未知的制作，没有标记)在我的Raspberry Pi上检测不到 .

这是lsusb的输出

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.

Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.

Bus 001 Device 004: ID 0c45:608f Microdia PC Camera (SN9C103 + OV7630)

Bus 001 Device 005: ID 1267:0103 Logic3 / SpectraVideo plc G-720 Keyboard

但是当我运行动作时，使用/ dev / video0和唯一的默认配置会改变分辨率并关闭网络摄像头主机，以便我可以在网络上传输它 . 这是我运行动作时的日志

相机上的指示灯在开始时亮起然后再次熄灭，是否有人认出我遇到的任何错误？

谢谢！
