USB 3.0 Bandwidth Limit Problem

[DaneLLL]

Hi,
Here is discussion about USB bandwidth on Jetson Nano:

connected more than two usb cameras problem on deepstream-app (Jetson Nano Dev Kit)

Hi, With further investigation, we found bandwidth limitation is hit in using USB2(High-Speed) cameras. High-Speed limit is 480Mbps. In the test, two E-Con See3CAM_CU135 are USB3(Super-Speed) cameras. Please use USB3 cameras to get 5Gbps bandwidth.

So if you plugin in two D435, each camera should have 2.5Gbps bandwidth.
However, the power could be a potential concern. We have tried to connect one E-Con See3CAM CU135 camera and one fan. When the fan is running, CU135 camera cannot reach target framerate. This might also happen while connecting two D435.
