A:AnswerI believe it is hit and miss with controllers. Play with it as soon as you purchase because usually if it had a defect, you could feel it within 5 days. Return it once you determine it is defective.
A:AnswerYes, the transfer rate is limited to 480 Mbps. Though, the controller doesn't need to send any more data to the console than that, response time is still 1-2 Milliseconds whether it uses USB 3.0 or USB 2.0. Hope that helped.
