Micromax A57 is not displayed in Eclipse Device List
After a long search, finally I made my Micromax A57 to connect with eclipse and made it to suit for development. 


Installed Moborobo (All in one Android smart phone management tool).
Perform stop -server / start -server using ADB. 
Reboot the device.
Restart the eclipse. 


Device got detected.(Eclipse - list of adb devices)

List of attached devices: 

Hope, this would be surely helpful.

Thanks
