Could be a few problems. Maybe the cable provided has an issue - you could try it on a different device, if you have one. Make sure your computer has USB 3.0 ports, and make sure the drivers are up to date. You can look up your computer model and go to the manufacture site for the official drivers. Try different USB ports if the computer has more than one. Often the ports on the desktop front connect to a less-reliable 3rd-party USB controller, while the ones on the back of a desktop go straight to the standard Intel controller.
