Cameras randomly disconnect or don't run

Question

I am making a surveillance system and it requires at least 6 cameras. Currently I have connected 4 to my PC by USB. I am using supplementary power for each camera since the USB output of my PC is sometimes not capable of delivering enough power.

currently they show up like this

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

However, when ruining the code only 3 shows up or 4 but one stops working immediately. I have try several combinations of USB ports and they keep failing. All the cameras are from the same brand and have identical characteristics the only difference is the path.
