  • Hi,

    Welcome to the Community. Try uninstalling the USB root hubs. Click on start, right click on computer, click on properties, click on device manager, click on the symbol next to Universal Bus Controllers, right click on USB root hub and click on uninstall, you will see more than one USB root hub, uninstall all of them. Once uninstalled restart your computer, so windows reinstalls the driver, and then plug in the USB device.

    I also recommend you update your Chipset and Dell System Software.
