Hello, first I would like to apologize I don't have A LOT of PC knowledge, but can follow directions if clearly stated.
So, I have recently purchased a device that will not work properly unless plugged into a 3.0 USB PORT. (Yes, there is a USB 3.0 Cable) It works, and gives power to the device, just doesn't let the device run, in other wards it is most likely working as a 2.0 USB Port. This is the best I can really describe the situation if you have any other questions, please ask.
