Make the examples Error! on NCS2 - [Error 7] Toolkit Error: USB Failure. Code: Error opening device

hi, 

I have NCS2 plugged in ubuntu 16.04 (running natively), I got several errors when I'm doing "make examples".

Dear Wenwai, 

are you using the NCSDK? NCS2 only works with OpenVINO, which can explain your error.

Best,

What version of the OpenVino SDK are you using? 

R5 seems to have fixed most of the "Error opening device" NCS issues.
