RT Software will ONLY work with their custom programmed FTDI cables. With that said, it's very simple to reprogram FTDI devices to have the RT Systems VID:PID and that should work just fine. Once done, you can program back the standard FTDI serial port VID:PID numbers.
Btw, I was reading the FT2 manual closer and on page 161, it seems the radio can be upgraded with a basic micro-USB cable or via the SCU-19 cable. I don't know if the radio can be programmed with the plain USB cable though.

I have a FT1D and had similar problem. Cable would not work with RT systems software.. had to use a micro sd card with RT program. Put card in radio after programming and then uploaded the program from sd card to radio.. worked well
