Jetson Nano B01 cant detect USB ports

[DaneLLL]

Hi,
There is bandwidth limitation of connecting multiple USB cameras to Jetson Nano devkit. Please refer to

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.

But from your description, it looks like the cameras cannot be enumerated. We have not seen this. The cameras should be detected and enumerated but may hit bandwidth limitation and fail to be launched.
