How to fix "This device can perform faster" in USB 3.0

If you are you getting a "This device can perform faster" error when you plug in your ZED camera, this means that the ZED is streaming video in USB 2.0. In this mode, maximum resolution is HD720 at 4 FPS and VGA at 12 FPS. There can be several reasons why the camera is in USB 2.0 mode:

USB 3.0 is running at USB 2.0 speed

USB 3.0 will work in USB 2.0 if:

  • In Windows device manager, the Intel(R) USB 3.0 Host Controller Switch Driver is not installed or disabled.
  • In BIOS, the USB 3.0 port is downgraded to USB 2.0.
  • You're using a laptop computer which is running on battery power.
  • The ZED is connected to a USB hub or via extender cable.

Different USB Port

Plug the ZED into another USB 3.0 port of your computer. Make sure that you have USB 3.0-capable hardware. USB 3.0 ports can be recognized by their blue receptacles. The cable must be pushed in all the way into the port.

Update USB driver

Download and install the newest driver for your USB controller. Getting updates to these drivers will depend on the manufacturer of your motherboard/computer. On Windows, you can update your driver by doing the following:

  1. On Windows, open "Device Manager." 
  2. Expand "Universal Serial Bus Controllers" and locate the USB 2.0 Root Hub Device.
  3. Press “Update Driver Software”.
  4. Unplug the ZED.
  5. Reboot Windows.
  6. Plug the camera into USB 3.0 port.

Note: On a laptop, do not install generic Intel drivers but download and install your OEM drivers.

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

  1. In "Device Manager", expand "Universal Serial Bus Controllers" and locate the USB 2.0 Root Hub Device.
  2. Press “Uninstall”. Continue with the un-installation process (do not delete the driver).
  3. Unplug the ZED.
  4. Reboot Windows.
  5. Plug the camera into USB 3.0 port. The driver should automatically install.

Direct connection

Make sure that the ZED is plugged directly into the computer rather than using USB hubs or extender cables, and remove other USB devices that may be using the USB bandwidth.

External PCIe USB host controller

Chipsets integrate different USB host controllers that vary in performance and throughput. An external PCIe host controller card is another method for adding high-performance USB 3.0 ports to your system.
