OpenCV VideoCapture.open() keep changing indexes

I'm trying to open my usb camera on my Raspberry Pi using the following code: 

VideoCapture capture;
capture.open(0);

The code can work perfectly one time but after running it again later I get:

HIGHGUI ERROR: V4L: index 0 is not correct!

without touching the camera or the code! Sometimes changing to capture.open(1); solves it but sometimes not. I read somewhere you can use (-1) and it will use the first camera it finds but that didn't work either.
