When using a USB hub to connect your USB devices like a webcam with your computer, you realize that it’s not working.

USB hubs need to be powered to be used with webcams

  • If your webcam is not working with a USB hub, it could be because the hub doesn’t have sufficient power, and thus, for webcams, you need to use powered hubs.

  • Theoretically, the bandwidth of a USB 2.0 Hub is limited to 80% of 480Mbps or ~60MBps, so a USB hub can divide the bandwidth across a maximum of three cameras.

  • However, the issue could also arise due to outdated drivers, or a problem with the webcam, USB port, or the OS itself.

  • Download DriverFix (verified download file).

  • Click Start Scan to find all problematic drivers.

  • Click Update Drivers to get new versions and avoid system malfunctionings.

This is a common situation and apparently, it may occur due to corrupt or outdated USB drivers. You may also encounter this issue if you are not using a powered hub.

Also, because certain external hard drives like webcams or flash drives are high-powered devices, they would need a powered hub. Otherwise, they may fail to work.

But if there’s a power surge in the USB port that’s preventing the webcam to work, you can follow our detailed guide for more details.

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.
