      no special drivers are needed for a USB flash drive , 
      Windows has all the necessary basic drivers required to recognize a USB drive .

      if it does not , it will automatically download the latest and the appropriate required .

      if its a new drive you bought , then i would recommend getting it replaced from the company .
      it might be a faulty one ( happens many a times ...) , 
      and then, no matter what you try , all will fail .

      on a passing by , 
      just try inserting the drive in the PC in safe mode . see if it detects then .
      you can also try checking the drive status using - GPart ( http://gparted.sourceforge.net/livecd.php  )
      its powerful drive manager which runs under Linux .

      try and see ...

    Hello, have you tried using a different usb port?  Usb ports in the back of you computer would be better.  If it is not recognized in any usb ports you can go to device manager and uninstall the usb drivers.  They will be reinstalled after you restart your computer.

    Have you checked in disk management if it shows there?  If it does, try assigning a drive letter to it.  Unplug it and then plug it back.

    Have you tried it in a different computer?  Sometimes, you can turn your computer off, also if there is a switch on the back of the power supply, turn it off too.  Unplug the power cable from your outlet/power bar to your computer for a few minutes.  Plug it back in, turn the switch on and start computer.  Try usb drive again.

    restart can solve the problem sometimes.
    try another pen drive in your PC, and try that 64 gb pendrive on another pc, to find out where is the problem exactly, in the pendrive or in the pc.
    If it is detected on another pc, it means you need to
    check for updates.
    and try to configure device manager.

    >in the device manager , where it shows as unrecognized device ,
    right click on it and then click on update drivers .
    and then click on let windows search for the best driver .

    >run the Windows Update for 3 or 4 times ,
    even if it says no updates found , do check for 3 or 4 times .

    this would enable the Windows to download and install the appropriate drivers .

    restart later . recommended .

    if it fails ,
    try logging in Safe Mode , and see if Windows is able to identify the Drive .

    >if it still fails . format it .
    i would recommend GPart Utiltity as the fail safe app for formatting the drive .
    you can also go for Easeus Partition Manager and then format it through it .

    replug and see .

    tell if more help needed ...
