And usb bandwith is not an issue, as I can capture 3 cameras and capture cards as long as they use 3 Unfortunately moving the cameras and their video capture devices to separate usb controllers does not resolve the issue.

Is this the root cause? And if so, is there a way around this limitation by writing a program to access the driver/deviceĭifferently in Win10? As you may suspect, these are generic drivers for $15 video capture devices, so contacting the manufacturer, or expecting updated drivers is a no-go.

So I assume that the driver is to blame for the lack of ability to have more than one identical video capture device operating at one time. However, I have successfully had 3 video capture devices running simultaneously they were 3 different types with 3 different drivers, so I doubt the usb bus or the PC is at fault. Having the two video streams (NTSC composite) running at the same time. It was suggested by others that the usb bus could not tolerate The 2 video capture devices are using the same driver, but do show up as two distinct devices to the program that displays the captured video.

Other, or, the video streams for both are corrupt. When they are both running, either one video stream works, and not the Either camera works when operating alone. On my Win10 laptop, if I have two composite cameras feeding to two external video capture devices, which are connected to the PC via usb bus.

I know very little about drivers, and I assume this is going to be a rhetorical question, but here goes.
