  1. Thank you for upload ing this, but please don't do so much background music. If people gets older the ability to " filter" voices and other sounds decrease. It is very hard to understand what you are saying. Anyway, keep up the good work!

  2. One thing he missed which was what was wrong with mine, is the actual usb stick/cable itself, with me, I was trying to connect my phone but came up with the error, tried everything he said but nothing worked, decided to swap the cable I was using to connect my phone and voila, it worked

  3. After u have done all the above as the help methods..i add in one more from my side which i solves today………..
    ONLY for PC…whatever windows u are in as long as all the 6-7 methods u tried not helping…
    Front with Back USB ports esp one set or wire cable is faulty…
    Power off system…unplug power plug as u are accessing the MOBO—-
    Pull out the blue cable USB out from your mobo (disable 1 by we disable the front USB ports first)
    connect back power source…
    POWER UP…and check in your device manager again to see if there is any more unknown device hidden…

    ***IF YES….again…do the same method…but put in the cable back and pull out the other one……..Power plug back..power on…again go to device manager to see again.For my case…MY USB 3.0 port is faulty but i am not using so i just unplug the cable…and everything goes back to normal… Hoping this final method helps u guys……….
