USB ports not providing enough power

Standard USB 3.0 ports come in low-power and high-power variants, supplying up to 150 mA and 900 mA respectively, while simultaneously transmitting data at Superspeed rates.

USB power issue

The ZED camera can draw up to 380 mA when connected to a computer. It may need more power than it is getting from the USB connection, resulting in several connection issues:

  • ZED camera cannot be detected by the system
  • Corrupted frames appear randomly in the video stream
  • Device is automatically disconnected by the system after a period of use

How to fix it

The best way to fix this issue is using the high-power USB 3.0 ports available on your computer. Try different ports, and avoid using USB hubs that are often not able to provide enough power for the device.
