Click "Properties" and select "Device Manager" from the screen that comes up.
Click on the type of USB device that uses the specific driver you plan on testing, such as "Universal Serial Bus Controllers," or "Sound, Video, and Game Controllers."
Look to see if there are any exclamations or question marks next to the name of the device. This will indicate whether the drivers have been installed properly or not.
Right-click on the name of the USB device and then "Properties." You should see a "Device Status" message saying, "This Device is Working Properly." If you do not, then you need to reinstall the drivers.
