Hello, I try to use 4 USB3 camera with Jetson NX. But I cannot get it work with the 4th camera. The camera are connected with a USB3 hub, and here is the output of lsusb -t /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=tegra-xusb/4p, 10000M |__ Port 3: Dev 2, If 0, Class=Hub, Driver=hub/4p…

Hi, It looks like each camera requests for > 1.25Gbps bandwidth so that the fourth camera doesn’t get enough bandwidth. You may check UVC driver and add debug prints to show the requested bandwidth of the cameras.
