I suspect that the problem is with the adapter itself.
I thought that if I connected just the adapter to the computer, at least the power led (green) was supposed to blink... And it is not blinking.
I tried both Xbee S1 that come with the Tweet-a-Watt kit and neither worked...

p.s. 1) The virtual COM port is successfully recognized by the computer with both Xbees...
2) If you have any problems visualizing the images please let me know
Thank you very much for the help!
