Ports with connected devices show a blue and red USB icon, while ports not currently in use show a blue USB icon. As you can see, the tree shows which ports have devices connected to them and which don't. (If you want to see the level of detail for yourself, check out the USB in Windows - FAQ page in the Microsoft Hardware Dev Center.) Using the toolĭespite the complexity of USB in Windows, the USB Device Viewer is easy to use for tracking down USB connections. Of course, the way USB works in Windows is far more technically detailed than my simple description, but I think you get the idea.
Furthermore, in addition to the external USB devices that you connect to your system, there are a number of devices integrated into the PC that can be connected via a USB connection, such as an SD Card reader or a webcam. That also means that one physical port will be represented by multiple ports in the tree. For example, a USB 2.0 port on your system will be connected to two host controllers-a USB 1.0 host controller and a USB 2.0 host controller. In a nutshell, the reason that there are so many items in the tree is that USB ports need to be able to support multiple USB versions. For example, the tree in Figure F shows seven host controllers and 30 ports, yet my computer has only eight external USB ports: two USB 2.0 ports on the front and six USB ports on the back-4 USB 2.0 and 2 USB 3.0 ports. You'll also notice that there are more host controllers, hubs, and ports shown in the tree than there appear to be in your system.

Figure E Once you isolate the files, you can uninstall the Windows Software Development Kit. Once you have done so, you can access the Programs And Features tool in the Control Panel and uninstall the Windows Software Development Kit, as shown in Figure E. Now, copy these two files to a folder of your choice.
Figure D Locate and select the two files that make up the USB Device Viewer tool. They make up the USB Device Viewer tool, as shown in Figure D. When you access the folder, locate and select these two files: usbview.exe If you are running a 64-bit version of Windows 10, navigate to: C:\Program Files (x86)\Windows Kits\10\Debuggers\圆4 If you are running a 32-bit version of Windows 10, navigate to: C:\Program Files (x86)\Windows Kits\10\Debuggers\x86
Once the Windows 10 SDK is installed, launch File Explorer and navigate to the folder that matches your operating system type. Figure C Make sure you select only the Debugging Tools For Windows check box. The procedure will take a few minutes to complete. Clear all the other check boxes, then click Install. On the opening screen, select the Debugging Tools For Windows check box, as shown in Figure C. When the download completes, locate and run the sdksetup.exe installation. Figure B You'll find the tool on the Windows 10 SDK page. To begin, head over to the Windows 10 SDK page on Microsoft's Windows Dev Center and click the Download The Standalone SDK button, shown in Figure B.
