Android phone (Lava-Iris 456) not recognizable to ADT.

I am developing an android app using ADT & I want to test my app on a real device instead of stimulator. I am using my Lava Iris 456 phone for this purpose. I have also enabled “USB Debugging” in settings->developer options but ADT is not recognizing my phone and not showing it. Suggest some to solve this issue.
