USB 3.0 Verification Method

Windows

On Windows, it is recommended to use a third-party tool to view USB status information. Download USB Device Tree Viewer to inspect the USB device.

After downloading, you can find the inserted camera in the left panel of the software.

Select the camera device you want to inspect. Detailed descriptions will be displayed on the right. Observe the following section to confirm if it is USB 3.0 or above.

The USB Version field should show 3.0, 3.2 Gen 1 (5 Gbps), USB 3.2 Gen 2 (10 Gbps), or higher.

Linux

Use the lsusb command to view the camera location.

In the image above, Bus 004 Device 002/004 represents the event camera, and Bus 004 Device 003 represents the fusion camera.

Use the lsusb -t command to find the USB device corresponding to the Bus and Device numbers, as shown below:

If it displays 480M, it indicates USB 2.0.

Dvsense event cameras and fusion cameras require a speed of 2000M or higher to operate normally.
