USB Debugging for the Samsung Galaxy Y?

I have connected Samsung Galaxy Y phone with Android Development Tool (ADT Eclipse) It doesn't recognize my device. I'm using window XP (64 bit) operating system. I have also made the USB Debugging mode enabled, by Going to Settings->Applications->Development. But no reaction, I have referred this link too no use. I have also checked the Security -> Unknown Sources. Simply, I want to use my mobile like emulator by connecting with IDE. But Its not working. If don't know its possible or not.
