Think it depends on which version of Framaroot you are trying on what firmware is on the device. For the USB Debugging connection to the PC, this is most likely from driver issues. Check your Device Manager to see if there is a yellow exclamation mark next to the device name. As far as rooting goes, I would suggest Kingo Root.
Install, open as admin, and follow the instructions. It might even be able to download and install the drivers for you (it does that for some devices, but am not familiar with Micromax stuff) If not, you might check out installing PDANet as it has drivers for about everything.
