Since your platform can have both USB 2.0 and USB 3.0 controllers, it's useful to check which controller the USB device is connected to. Follow these steps:
- Connect a USB 3.0 thumb drive (USB Mass Storage Device) to one of the Intel USB 3.0 ports.
- In Device Manager, click View, and click Devices by connection.
- In Devices by connection view, you can easily see the USB Mass Storage device under the Intel® USB 3.0 eXtensible Host Controller category.
