Can OBS support 2 webcams with same brand but different model at the same time?

Trouble of configuring 2 same brand but different model webcam. OBS can see 2 cameras but only can configure one. Configured one but the other go blank. Is it because they are using the same driver? Anyway to get around?

Are you using USB hubs at all?

Yes, it is I'm using a C270, C8920, and C922
Just make sure they are on different USB hubs Two 1080p cams can overload the bandwidth of a USB hub

Yes they are on the same USB hub as I only have one USB port on my notebook.

I only have one USB port on my notebook, so I have to use a USB hub. The cams are 720p

The use of the usb hub is what's ultimately breaking things. webcams take a lot of usb bandwidth, and having them on a hub means there's only enough for one.

Then any suggestion how can I use multi cams if I only have one usb port on my notebook?

i had used 3 Logitech cam at the same time with not problem. when you add them just make sure you pic the right camera. at this moment i'm using a c920 and a c922 with not problem. but I'm in windows now but had them working fine on my mac

The problem isn't the multiple cameras at the same time in general.
It's that the usb capabilities of their computer can't handle multiple cameras at the same time.

I used a mac before and only had one usb port where I connected a usb hub and my two camera and my mic were connected to that usb hub

Is it USB 2, 3, or 3.2 Vary different bandwidths

That was you and that was on mac

I think it may be a bit more complicated than that. I encountered this problem right off and have been looking for a solution.
We are running two OBSBot cameras using a laptop (with limited USB ports) [Intel 11th gen i7 with windows 11 pro] and need to use a hub. Plugging the camera's into the hub, other programs seemed to recognize them and were able to control them (the OBSBot software in particular). But OBS Studio, although seeing them would not show any input from either. Unplugging one and mounting it on another USB port (or USB Hub in a different port) and immediately had video in OBS Studio! This is a huge pending problem... they are putting fewer and fewer "plugs" on laptops, expecting that the users will use a hub... for not only USB devices but card readers, eithernet connections, hdmi connections, wireless mouse...!

To have OBS Studio need a configuration of only one camera per USB port will be a serious problem.

A question to anyone out there... have they tried connecting multiple cameras to a powered hub? Anyone have any thoughts on whether that would help?

Powered hub vs unpowered hub won't help when it's a bandwidth issue.
