Intro :

If you are trying to flash custom Kernal/ROM and getting an error of your device not been detected by your PC running on windows 8 then you will need to install the USB/ADB/Device drivers for your handsets.
This can be done by using following tutorial.

!! UPDATE !!
Date : 20 - April - 2014

Those who are on windows 8.1 and having trouble to install drivers will have to download and install windows 8.1 update from here and once you install that you can follow this guide.
Step 1 :

Suppose you are trying to install custom Kernal on windows 8 and you stuck at this screen and nothing happens even if you connect your device in fastboot mode then its due to missing drivers.

Step 2 :

So now lets get started. Press "Start Key/Windows Key + C" or move your cursor to top right corner of the screen to activate the Charm Bar and click on "Settings Button" as shown in following figure.

Step 3 :

Now the setting panel will open. Click "Change PC Settings" from the bottom as shown.

Step 6 :

In troubleshoot click on "Advance Options" .

Step 7 :

Step 8 :
