About the specifications of Jetson Xavier NX (USBcamera)

[kazuki.yumiba]

I want to connect multiple USB cameras to Jetson xavier NX and run the AI algorithm.
With two USB cameras, it works fine, but with three USB cameras, it doesn’t work because the bandwidth is insufficient.

Error message: No space left on device

Camera used: ELP-USBFHD01M-BL28
High frame rate MJPEG 30 fps @ 1920 (H) x 1080 (V)
USB2.0

Does anyone know the solution?

Hi,
The behavior is same as on Jetson Nano. Please check the explanation in

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.

We suggest use USB3 cameras to get more bandwidth.
