I know I m 4 years late but my answer is for anyone who may not have figured it out  I m using a Samsung Galaxy S6  what worked for me was    Disable USB debugging Disable Developer mode Unplug the device from the USB cable Re-enable Developer mode Re-enable USB debugging Reconnect the USB cable to your device   It is important you do it in this order as it didn t work until it was done in this order

Looks like the installed driver was in bad state  Here is what I did to make it work    Delete the device from Device Manager  Rescan for hardware changes   Slate 21  will show up with  Unknown driver  status  Click on  Update Driver  and select  extras google usb driver Device Manager will find the driver and warn you about installing it  Select  Yes     This time the device got installed properly   Note that I didn t have to modify winusb inf file or update any other driver   Hope this helps

In my case  which none of the answers above stated   If your device is using the miniUsb connector  make sure you are using a cable that is not charge-only   I became accustom to using developing with a newer Usb-C device and could not fathom a charge-only cable got mixed with my pack especially since there is no visible way to tell the difference   Before you uninstall and go through a nightmare of driver reinstall and android menu options   Try a different cable first
