Issues with Multiple Video Capture Cards

[MJFanatic]

Hi,
I’ve been running two of the same HDMI capture cards, and one webcam without issues. However, every time windows updates it creates issues with one of the two HDMI capture cards. One will work, and the other will simply show black. The first time this happened after about 4 hours of playing with it, it started to work perfectly. Flash forward to the most recent windows update and the same issue is happening only this time I can’t seem to make it work.
I’ve tried changing USB ports, re-creating all the scenes, deactivating and reactivating manually, and nothing seems to fix it.
Anyone have any solutions that I could try?

Got it working, If anyone else of having the same or similar issue it was with a USB Hub, plugged the capture cards into the USB ports on the computer, launched OBS, then replugged in the USB hub. It all works fine now. ‍

For us, I have to play with the properties of the 2 video capture devices. In other words, move one source to the 'other' video capture USB and the other source to another capture device. Usually a couple of swaps works. I think the root cause is that both of our video capture devices have the same name - the generic USB 3 Video Capture so OBS is not uniquely associating a capture box with a source.
