Thank you for leaving us the product review. Sorry for the disappointment.
Based on your description, a defective USB 3.0 cable or a hub could be a reason. Meanwhile, it is strongly recommended to update the driver and firmware for your USB 3.0 host controller to the latest version, for which you may contact your PC supplier. This ensures a smooth and reliable experience when using any USB based device (either 2.0 or 3.0) with the USB 3.0 host controller.
To speed things up, could you please email us update directly at email@example.com with your Amazon order # and review, we are more than happy to exchange a new one without hassle once the hub defect is confirmed.
