How can I use Jeppensen Flight controls?

[GadgetPa]

I have got a complete Jeppesen flight training system.  Circa 2000.  I want to use the controls, Yoke, Rudder Pedals, Radio stack, on a newer USB only Windows 7 pc with FSX.  I have the Radio/controls box hooked up to usb through a converter.  Same with the throttles and yoke.  I've download and installed the FSUIPC4.exe, serial port and the serial test utility.  When I load FSX, it recognizes the driver and gives me a status screen.  Got a green checkmark on FSUIPC4 with "Okay.  All options available".  Have a green checkmark next to Com1 open.  All controls listed as 'X'.  Last clue is I at least have power getting to the radio stack (red led on).  I'm pretty sure this can be done.  Does anyone think I'm close?  Or..  Am I way off the track?
