Conclusion: Just follow the video No:1 for helping rectify the issue. This issue is at high level to do with usb 3.0 and WiFi / Wireless devices. Even the very heavy priced items like Belkin there are usb 2.0 ports mainly to accomodate the same. We also have hubs with usb 2.0 if you would like this swapped but the above solution is very simple and as you can see from the comments its humorous but it works and does not have any side effects.
