Question / Help Can't get 3x Dazzle DVC100

[Couin]

Hi :)

I would replace my poor quality webcam for Dazzle + Analog camera.
So I got a Dazzle DVC100 and a camera and it works nice.
As well as I would use multiples cameras, I bought 2 others DVC100.

I can run a scene with one camera over a small zone of the first camera. So 2 DVC100 are OK.

I plugged the third, I get well the 3 DVC100 listed in OBS but I can only get preview on only 2 (of course, the all 3 Dazzles are OK if I test only with 2 plugged, for exemple the first + third). Even pluggin on other USB ports, I still get the same problem.

If I test with AMCAP (small software provided with a usb webcam), I can get the preview (one a same time of course) even with the 3 DVC100 are plugged. Juste select each one dislays its video source.

Any ideas ? :)

Thanks

I built a computer to support 3 DVC 100s and was having the same issue. From what I gathered, it runs out of USB endpoints. You can sometimes get by with switching which USB ports you are using. They actually work best with 2.0 from my experience. That is what they are built for and it uses fewer endpoints.
