Device open Error

[naufil601]

Hi,

I'm using NCS2 with Ubuntu 16.04. I have installed ncsdk2 as well.
However, I'm facing this error (W: [ 0] ncDeviceOpen:528 ncDeviceOpen() XLinkBootRemote returned error 3) when I try to run example using command (python3 ./detectionExample/Main.py --image ./data/dog.jpg).

Please help me solve this error. I have attached the error screenshot along with the usb port details
