Question / Help 3 Video Capture Devices

[AshMarks]

I'm having trouble getting 3 video devices to work. I've got a Dazzle DVC 100, a GV-USB2, and a Logitech c260 webcam, and I want them all to display at the same time; if I use only 1 or 2 of them at a time they work perfectly, but having all three of them running at once is almost hopeless. I've gotten it to work a few times over the course of a few hours, but once I stop the preview it ceases working. Any idea what might be wrong would be appreciated.

Looking at the performance numbers, it's probably to do with USB limitations OR your system's processor limits.

I have intel Z87 and Z97 based motherboards that are able to do 3-5 capture devices fine. (Tested the Z97 motherboard with 5 logitech C920 cameras)

Dang, I was afraid of that. My task manager CPU reading isn't going any higher than 45%, and my temperatures aren't going above 50 degrees Celsius, so I don't think it should be my processor's fault, but you never know. Would you happen to know of any way to soften the load, other than the obvious "unplug some USB devices" and "upgrade your CPU"?

You can lower the resolution of your devices to lower the usb bandwidth usage of them. Also try connecting them to different USB Hubs if your Mainboard offers more than one. (Front and Back ports for example sometimes use different chips/hubs).
In general I would probably recommend to use internal capture cards to be on the safe side.

I installed new usb ports into a new connection on my motherboard and the issue was solved, the bandwidth seemed to be overloading just going through my back IO ports. Thanks for the help and quick responses!
