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.
