If you have multiple C920 webcams connected and are using them simultaneously, you may experience the following issues:

• Unable to adjust settings on individual cameras
• Blue screen crash when launching OSB

These issues can be the result of a problem with the driver. You can switch from the Logitech drivers to generic drivers to resolve the issue. 

NOTE: Because the use of Logitech Webcam Software (LWS) requires the Logitech drivers, you will not be able to use LWS if you plan to use multiple webcams simultaneously. In addition to the fix detailed below, we recommend the following software if you plan to use multiple C920 webcams simultaneously:

• Microsoft Camera App on Windows 8 and Windows 10 (installed by default on Windows 10)
• OBS or XSplit Broadcaster with Windows 7
• OBS or Quicktime with Mac

NOTE: You can always revert back to the Logitech drivers by reinstalling LWS from the Logitech website.

How to switch from Logitech to generic drivers

NOTE: You will need an Administrator account to perform the following steps.

IMPORTANT: Before you start, make sure your C920 webcam(s) are connected directly to a USB port on your motherboard and not connected to a USB hub as it can cause additional issues. 

1. Open Device Manager — In the Windows search box (on the toolbar in Windows 10 and in the Start menu on older versions of Windows), type Device Manager.
2. In Device Manager, click Imaging devices, then Logitech HD Pro Webcam C920.

   

3. Right-click Logitech HD Pro Webcam C920, then click Update Driver.

   

4. Select Browse my computer for driver software.

   

5. Select Let me pick from a list of available drivers.

   

6. Under "Select the device driver you want to install for this hardware", select the option to update the generic USB driver.

   

7. Once you have installed the generic driver, we recommend rebooting your computer. Windows will prompt you to reboot on the first driver, but you can wait until you have installed the drivers for all of your C920 webcams before you reboot. 

   

   
   NOTE: We highly recommend you install and use the Logitech Gaming Software (LGS) for controlling your C920 webcams. You can download the latest software here.
