I'm using a laptop, after I installed facerig it says can't detect my camara. I checked my camara driver. There is only one driver "Facerig vitural camara" I remember there should be another driver"USB camara 2.0". I don't know why I only have a vitural camara now. I'm just using the camara of the laptop. And now I'm unable to open the camara due to lack of the"usb 2.0 camara"
