Do I need a powered USB hub for a webcam?

While the powered USB hubs draw their power from an electrical outlet, the non-powered USB hubs draw their power from the computer connection.

USB hubs are perfect for low-powered devices like mice and keyboards. But for high-powered devices like webcams and flash drives, it may not work properly.

You can also use multiple webcams with powered USB hubs, and divide the available bandwidth across three cameras.

However, if none of the above methods work, you can create a system restore point on Windows 11 and perform a system restore to go revert your PC to a previous working state.

If this does not help, you can also reset your Windows 11 PC and check if this helps fix the webcam not working with the USB hub issue.
