Forcing windows 8.1 to install google usb drivers for adb access

http://stackoverflow.com/a/25576781/2718295

I had the following problem: I had a Android phone without drivers, and it could not be recognized by the Windows 8.1. Neither as phone, neither as USB storage device. I searched Device manager. I opened Device manager, I right click on Android Phone->Android Composite Interface. I selected "Update Driver Software" I choose "Browse My Computer for Driver Software" Then I choose "Let me pick from a list of devices" I selected "USB Composite Device" A new USB device is added to the list, and I can connect to my phone using adb and Android SDK. Also I can use the phone as storage device. Good luck
