It should be a device on your computer that does not have a driver. If you open the Device Manager (devmgmt.msc) and look you will see the same thing. It may be hard to determine exactly what the device is, but you might try right clicking and see if it tells you anything, like a description or a number associated with the device. It might be some part of the chipset that needs an additional driver, or a card reader or some other type of device built into an external device.
