摄像机随机断开连接或不运行

Question

我正在进行监视系统，它至少需要6台摄像机。目前，我已经通过USB连接了4个。我正在为每个相机使用补充功率，因为​​我的PC的USB输出有时无法提供足够的功率。

但是，他们像这样出现时出现时

kc@kc-B550I-AORUS-PRO-AX:~$ v4l2-ctl --list-devices
3.0 USB Camera: 3.0 USB Camera (usb-0000:05:00.0-1):
    /dev/video4
    /dev/video5

3.0 USB Camera: 3.0 USB Camera (usb-0000:0b:00.3-1):
    /dev/video6
    /dev/video7

3.0 USB Camera: 3.0 USB Camera (usb-0000:0b:00.3-2):
    /dev/video0
    /dev/video1

3.0 USB Camera: 3.0 USB Camera (usb-0000:0b:00.3-4):
    /dev/video2
    /dev/video3

，当仅显示3个代码时，出现了3个或4个出现，但一个停止立即工作。我尝试了几种USB端口的组合，并且它们不断失败。所有相机都来自同一品牌，并且具有相同的特征，唯一的区别是路径。
