The USB Root Hub, which stands for "Universal Serial Bus Root Hub," provides us with the ability to link our computers with external devices, such as keyboards, external storage and printers. When a USB device need troubleshooting, you need to be able to locate the USB Root Hub within Device Manager. If you are not familiar with accessing Device Manager in Windows, do not worry. Microsoft has made this process simple enough so that all users can do it.
Go to the "Start" button, which is found in the bottom-left corner of the screen. There is usually a Windows logo with four colourful square-like shapes on the button. Click on the button when you have located it.
Right-click on "My Computer," then select "Properties" from the list that appears from the pop-up menu. This will take you to the Control Panel's "System" screen.
Click on "Device Manager" from the left side of that screen. When you are asked if you would like to proceed, click "Continue."
Go to "Universal Serial Bus Controllers" and double-click on it. This will expand to show you all of the various USB Root Hub connections on your machine, as well as the Universal Host Controllers.
Right-click on a USB Root Hub name from that screen to update drivers, disable, uninstall or access the "Properties" screen. The "Properties" screen will provide multiple tabs that allow you to make changes to the performance of the USB Root Hub in greater detail.
