MGM Programming problems

Why did you keep to use the Tx programming method
The USB COM is suppose to simplify the programming task alot.
And for the price of this little programing device, don't know why lot of people keep to use the Tx for programming this controler.

I've since ordered the USBcom+ and will try it when I next get the chance, although I'm in essence having a problem simply pairing the device with my Tx. On a fundamental level, you have to get the ESC to recognize the end points of the Tx, no?
