ZED camera not recognized as USB 3.0 device

The ZED is a UVC-compatible USB camera. It is automatically recognized by Windows, Linux and OS X which all ship with a built-in UVC driver.

If you are you getting a “USB device not recognized” error when you plug in your ZED camera, please try the following:

Plug the ZED again

After getting the error notification, unplug the ZED and plug it again to the same port. Try this same technique several times, and make sure the cable connection is pushed in all the way into the port.

If this works, it might be a problem of loading the device driver at the time of plugging the camera into your PC.

Try a different port

Plug the ZED into another high-speed and high-power USB 3.0 port of your computer. Make sure that it is a USB 3.0-capable port, otherwise the camera will work in USB 2.0 backward-compatible mode with reduced resolution and frame rate. USB 3.0 ports can be recognized by its blue receptacle. Regarding power, please read our article on USB power issues. If possible, check the connection with another PC.

Remove hubs and extender cables

Remove any USB hub or extender cable, and plug the ZED directly into the computer. Remove other USB devices that may be sharing the USB bandwidth. 

Check your OS

The ZED is compatible with Windows 7, 8, 10 and Linux Ubuntu LTS versions (16.04).

Scan for hardware changes

On Windows, use Device Manager to scan for hardware changes. After your computer scans for hardware changes, it might recognize the ZED that is connected to your USB port.

To scan for hardware changes, follow these steps:

  1. Open Device Manager.
  2. In Device Manager, click your computer so that it is highlighted.
  3. Click Action, and then click Scan for hardware changes.
  4. Check if the ZED is now detected.

Reinstall Driver

If possible, download and install the newest chipset driver for your motherboard. Getting updates to these drivers will depend on the manufacturer of your motherboard/computer.

If you're unable to obtain a new driver, continue with these steps.

  1. On Windows, open Device Manager.
  2. Expand Universal Serial Bus Controllers.
  3. Press “Uninstall” for each USB controller that is listed under Universal Serial Bus controllers. Continue with the un-installation process (do not delete the driver).
  4. Unplug the ZED.
  5. Reboot Windows.
  6. Plug the camera into USB 3.0 port. The driver should automatically install.

Power Management and USB Controller

If none of these methods worked for you, you can disable the Selective Suspend feature. However, be aware that when the Selective Suspend feature is disabled, USB devices will continue to use power while connected to the computer.

  1. Open the Device Manager.
  2. Expand Universal Serial Bus controllers.
  3. Right-click each entry titled USB Root Hub and select "Properties."
  4. Change to the "Power Management" tab.
  5. Uncheck the check box next to "Allow the computer to turn off this device to save power."
  6. Press "OK."
  7. Repeat this for each USB Root Hub entry.
  8. Reboot the computer.

 

Known issue with USB 3.0 devices: On Windows 8 and 10, trying to reboot with a USB 3.0 device attached can prevent the OS from starting. In this case, unplug the device before rebooting.
