It seems so obvious to me facing this problem.Before 3-4 days ago i have just updated my a99 from kitkat 4.4.2 to Lollipop 5.0 from the official software updater in the phone.
Before updation,I can able to debug my phone and adb just listed my phone.
But after that update still i have tried different drivers like Universal Adb installer from ClockWorkMod and also Google's official adb drivers.
And still my device is shown in the device manager.But "adb devices".Never shows my device.
Hoping a better answer.
