Question / Help Logitech C920 Randomly Disconnects/Hangs

Hey everyone,

I have searched the internet and some of the OBS forums and found out that the Logitech C920 has some weird interaction with Win10 and OBS. Right off the bat, I had issues as soon as I took the camera out of the box.

After some basic troubleshooting, note that: every case seemed unique,

1. I found that you had to install the Webcam using the Default Windows USB drivers in order to avoid the Logitech Drivers to interfere with your Windows OS (Resulting in the OS not even being able to find your camera), THEN you can install the DRIVERS ONLY not the SOFTWARE as it also causes interference with OBS

2. Another fix was to edit a BooleanValue in the Registry after following links towards the Win10 update screwing cameras in the process

3. Lastly I got everything to work but simply checking "Device Manager" and seeing whether the Imaging Device was correctly located. And simply unplugging and replugging the Webcam in

*[It seems to also be interfering with some of my USBs (For ex: having the camera plugged + a blue snowball mic + an SD card reader seems to cause interferences)]*

Now the only issue left is that the camera will start hanging/dying in mid-recording even thought it can work perfectly fine for a while. I can easily solve this by replugging the camera and activating/disable the camera in the scene...

This is however very irritating for recording purposes as it can potentially botch up an hour long recording. Has anyone else encountered this issue or have a working solution other my rather primitive one at the moment?

OBS-Studio 21.0.1 (64-bit Windows)

I think this is just Logitech. I've got some issues occurring with my C615 as well.
Apparenty it's a program called Personify, but I don't know where it is or why it got installed, as my webcam isn't even fancy enough to use the feature.

This may be too late, as the last known responses are from 2018. However I was extremely frustrated as I was having this issue every time I broadcasted and tried EVERYTHING! and here is the solution that fixed my problem, for any of you who may come across this thread with the same problem. Suprisingly, its still the second or third link on google. Here goes!

Download Logitech Capture

Before opening your OBS, open Logitech capture and set all your lighting, resolution, frequency EVERYTHING in Capture

In your OBS, when you add a video input device, rather than select the webcam itself you need to select Logi Capture instead.

This fixed my problem completely, I have streamed 4 times since doing this, no hang ups, no disconnects. My only thing is that the newest and latest version of Capture would just freeze or not load at all after downloading. If this happens to you, downloading an older version of the software worked for me, and I just refused any software updates for now.

I hope this helped, I am sorry the reply is so late.

I'm going to add this one last time, as I found out one more thing that may be helpful to the users:

If you use Discord during your stream, I found that if I have Discord open before I open OBS or capture, the camera permissions are given to Discord first, and will not let you load up the camera settings properly. Revised instructions as follows:

1. If Discord automatically boots up on start up, make sure you fully close the program. That could be a task manager thing, or just close it by clicking the icon in the taskbar tray and click Quit Discord.

2. Open Logitech Capture and set all your configurations

3. Open your OBS and select your video capture device as Logi Capture. NOT THE WEBCAM ITSELF.


All of my issues with using my C920 to stream have been fully resolved.

I don't know if you'll reply, but hopefully someone can. I found this thread and thought I find my solution as this was the exact issue I was having in OBS.

I followed the instruction to download Logitech capture, and yes it no longer freezes (hooray) but there is a slight delay with the webcam and my voice, and I know I can move my mic delay to fit, but I was wondering if there was a reason for the delay?

Thanks in advance.

The fix for me I found was related to having more than one scene and camera was being used by another scene.

I will try this as I did have another source with just the webcam. But it will be silly if this is the problem, as if i wanted to stream or what not I would not be able to due to this. But thanks for any solutions!

I have 20+ scenes, with about 1/3+ having the same Logitech C920 webcam (which I believe I duplicated source in subsequent scenes).

Wanted to add to this for the archives. OBS randomly disconnects from every camera I have tried. An IP camera, a webcam, and a GoPro using a capture card. It's just a fact, it "disconnects cameras".

A solution for non-Logitech users (and Logitech too) is to use SplitCam as a virtual webcam first, then connect OBS to the SplitCam virtual camera. Never, not once, does it disconnect (IP camera, webcam, and GoPro via capture card). SplitCam is free and super easy.

That's all I've got to contribute!

Also for the archive
I can say my experience, with a computer with plenty of spare horsepower, does NOT have this issue... ever. Even on an older decent system that I drove to CPU overload, I'd have other issues and still no camera disconnect. As such, I highly suspect Versionist's issue is with their PC/OS, not OBS

Maybe (or even probably)! But that's my reality. If someone else has that reality, maybe this fixes it.

However, I doubt my copy of Windows 10 is special. And it feels weird when one program doesn't disconnect, but another does in three different scenarios.

By indicating your PC/OS, I'm not referring to Win10. Rather, the settings being used in Win10. I disable a whole bunch of default system/services/privacy invading, etc settings in all OSes, and turn off eye-candy, etc. ie.. I know exactly what I'm doing, and I optimize my operating system for security (somewhat) and performance. And not all motherboards are created equal. So, OBS, doing real-time video encoding, which is very demanding. So, easy to over-load a system and unless you are doing real-time monitoring of your hardware resource utilization, and understand how the OS and hardware interact, it is very easy to overlook an overloaded situation, and the 'instability' (crashes/disconnects, etc) that follow
