I just plugged my MGM to the usbcom and it worked fine using the setup they list.

Perhaps the ESC is not seeing the neutral correctly and won't arm. Have you tried to calibrate it? (ie set all EPA and trims to 0, then turn on ESC w/ full throttle)

My MGM was an opto, for the USBCOM, I needed to plug a battery in, plug the CC_02 cable into the usbcom, then turn on esc switch to on. There are LEDs on the usbcom you can watch as well. When just plugged into the usb port a green led flashes. When the CC_02 cable is plugged in properly a red led flashes (so that the green and red now flash once back and forth...red, green, red, green..)

When you turn on the esc power, the leds now flash very fast , like a HDD LED on your comp does when you write a big file to it. The software should say the esc is online now. Make sure you have installed all the software to the comp first before doing this.
You may need to widen the neutral range, but it may take some playing with in the SW.

Failing that... you can reset all the settings in the esc by holding full thr while turning on the esc for ~10secs. You may have to hit Rev when it prompts. Read the manual for the proper directions.

BTW, I was using a Futaba FASST, with the THR channel set to REV.
