Remember to disable Driver Signature Enforcement on Windows 8.
1) Press the Win + C keyboard combination to bring up the Charms Bar, then click on the Settings Charm.

3) When the Control Panel opens, switch over to the “Update & recovery” section.
4) Then click on the Recovery option on the left hand side.
5) Once selected, you will see an advanced startup section appear on the right hand side. You will need to click on the “Restart now” button.
6) Once your Computer has rebooted you will need to choose the Troubleshoot option.
7) Then head into Advanced options.
8) Then Startup Settings.
9) Since we are modifying boot time configuration settings, you will need to restart your Computer one last time.
10) You will be given a list of startup settings that you can change (press the F7 key).
OTHER STEPS :
Right click and select Update Device Driver Software.
Select Browse my computer for driver software.
Select Let me pick from a list of drivers installed on my computer.
Select Show all and click next.
Click Have Disk, then Browse.
Go to your extracted folder and go into it, until a file called (android_winusb.inf ... for example) is there. Double click that.
Click OK and then Next (If it says not signed, just click next anyway).
Wait and if it says not signed, click install drivers anyway.
:-)
