OBS works with only 1 cam?

[rudike6]

Hello.

I have installed OBS, newest release on my Windows computer(Windows 11). I know people who have three or more cams in OBS, but i can only use 1 cam?

I have cam 1 turned on, and it gives signal. Works very nice.
But, if i add video device 2, it can't activate. On the webcam, camera 2 there's a led that show you if the cam is turned on.
The led stays off and there's no signal.

Streamlabs Desktop works with two cams, but i want OBS.
Can i fix this?

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

It's hardware problem, buy device e.g. pcie card with usb, but check how many usb host is installed.
One usb host use 5 Gb/s, one camera uncompressed 1080p60 is 3 Gb/s.
Or use camera with compressed video signal.
