Can`t use USB Hub Connect three camera modules at the same time?

When we connect three camera modules at the same time (using USB Hub), can only read the data of two camera modules, after add additional power supply for USB Hub, the problem remains,
we have test this usb hub on our desktop,its can bring up four same camera, but when use the same code and camera deployed on AGX, has such problems,
How to solve the problem of can`t bring up more than two camera(usb hub) at the same time?What causes it?

Could you check if the USB hub is running as USB3.0 mode. Also have a check if v4l2-ctl --list-devices get all USB cam.

Also need USB 3.0 camera too.
