Can't get MGM controller to be seen by PC, what did RCMike do?

I'm also having this problem with a brand new controller. I have tried it over and over with no luck. I have the USB com cable. When I get every thing plugged in, I do get a green blinking light. I get the chime on my PC that a USB is connected. The ESC never goes online though! WTF!!! Very frustrating!!! Does anyone have a remedy?
