Do you have a second micro-B cable? Plug in both if you do, and you should see both in the Ports menu in the "device manager" utility, one as a regular com port, and the other as a virtual com port. Also, do you have the tiny switch on the side of the board between the USB and the inner micro-B connector in the micro-B connector position? Finally, when you connect via Putty, you have to hit return at least once to get the boards attention. If still no luck, please check back. Bunch of people here who can help.
Thanks for your quick response.
I Will try you suggestions.
i Am optimistic..
Found out later that day that I can run Arduino programs using the micro usb closest to 12v power adapter port.
also so noted that led will not light up when 12v power is only source.
Main issue is that Putty connection is not working.
You use the outer port to communicate via Putty, and use the COM port that is not the one you use with Arduino programming. Note that you do have to use external power when communicating with Putty, not with Arduino. Once you bring up Putty, you have to hit enter a couple of times, don't forget that part.
If your board is working with the Arduino IDE, then the board is obviously working. I expect you will get there with it shortly!
Note that you do have to use external power when communicating with Putty, not with Arduino.

Both not quite true. PuTTy over "outer" serial works just fine. It's just if you are using the full USB on Arduino breakout board (e.g. in order to puTTy ssh via USB eth dongle) that you'd have to switch off the micro USB and hence would need external power
The "enter a couple of times" one seems resolved with latest firmware - at least I haven't seen it any longer for quite some time
