Jevois detected but only shows video for 1 or 2 seconds

The camera is detected shortly after plugging it in.  Using Javois inventor 0.5.0, the live image from the camera is displayed for about 1 or 2 seconds.  Then the image goes away and it it says it is waiting for the camera.  In the bottom right hand corner it says the camera is connected.  Also device manager shows the camera is present always.

Usually, this means that your computer is not able to provide enough power to JeVois.

Thanks for mentioning that you are using a surface pro (tablet), this could be the problem.

Have a look here: http://jevois.org/doc/UserConnect.html

You may need to supplement the current that the tablet can provide, by using a Y cable, and connecting the power end of it either to a battery or a phone charger.

Thank you for the suggestion.  I added a 2.4A source to the second USB connector.  The camera now lasts for about 15 seconds.  This is too short to really explore however.  I will look at the code to see if perhaps something is wrong there.
Maybe your camera is having some hardware issue. Can you confirm that it works well on a desktop with USB 3.0 ports? Otherwise please email us at jevoisinc@gmail.com with your order number and we will ship you a new one to try out.
