Raspberry Pi 4, two HD Cameras connected to it, only one showing up

Our use case is rather unique in that the camera has its wires extended …, then into the raspberry pi via usb. However, the cameras wouldn’t work on another laptop if our connections were faulty in any way would they?

USB Low Light Camera Connection to Companion

Guys, my experience for what it’s worth: the RPi is much more sensitive to the cable type being a source of data corruption than (eg) a laptop. Cable length didn’t seem to matter, but the cable type is very important. I’ve had USB cameras that work fine on a laptop but not on the RPi; when I replace the cable with a better shielded high speed cable, they work fine. Keep the unshielded length at the camera end as short as possible.
