If it is a TRUE "HID" device, Windows XP will pop up a message about a new device found when you plug in the cable.
You must be running XP or greater. Also turn on the TX with the cable plugged in.
Some PPM interconnects require a driver program, such as JRPROPO, etc. to run, and getting these things to work is not trivial.
What is a true "HID" device? I'm grasping at straws here.
Hwlp! My only alternative is to actually get stick time at the field with an instructor.
