When I plug the USB 3.0 port of the monitor into my PC, I get a "Unknown USB Device (Device Descriptor Request Failed)". I tried multiple ports to the same result. Is there a generic USB I could download for this device?

    Hi Khii,

    It sounds like you are encountering an error "Unknown USB Device (Device Descriptor Request Failed)" on your Windows 10 which leads to an unworking keyboard. Sorry to hear this. The cause of this issue can be damaged/outdated driver, insufficient/unstable power supply, missing drive letter or drive letter conflict, etc.

    The solutions below can be tried to fix the error.

    1. Reinstall the USB driver.

    Press Windows + X and open the Device Manager > Expand the Universal Serial Bus Controllers > Right-click on the USB device which is not being recognized by Windows and select Properties > Click Uninstall > After that, visit the brand manufacturer's official website and download the latest version of the driver and install it.

    1. Disable Fast Startup.

    Open the Control Panel and set the view mode as big icons > Click on Power Options > Select Choose what the power buttons do in the left pane > Click on Change settings that are currently unavailable > Under Shutdown settings, uncheck the box next to Turn on fast startup (recommended) > Then click on the Save changes button > Restart your PC.

    1. Change Settings of USB Root Hub.

    Press Windows + X and open the Device Manager > Expand the Universal Serial Bus Controllers > Right-click on USB Root Hub and click Properties > Shift to the Power Management tab > Uncheck Allow the computer to turn off this device to save power and click OK.

    1. Check and repair disks.

    Type: cmd from the Windows search box > Right-click on Command Prompt and click Run as administrator > In the open command prompt window, enter: chkdsk C: /f /r [C: refers to the drive letter of the system disk, you can change the drive letter according to the actual location where the application is installed] > Hit Enter key to run the command.

    Are you using a USB-B to USB-A cable to connect the USB hub on the monitor?

    Yes, I am using the USB-B to USB-A (3.0) cable. Specifically, my PC is running Windows 11 and I am trying to connect the hub function of my XV272UP monitor to the PC. I have try uninstalling the generic USB driver and reinstalling it and nothing works.

    No driver needed. The USB-B to USB-A cable should connect the USB hub on the monitor to your computer.
