I am so close but yet so far from getting the radian's operational. I need to find an alternative solution for the FFUSB serial programmer. I purchased one similar to the picture in the manual and I am unable to get the pc and the radians to connect. When I connect the purchased USB Programmer, windows says everything is working properly. But when I connect it to the radians constantly connects and disconnects to the pc. I did follow the steps in the FAQ and installed the vitrual com port driver. I am running XP SP2 on this PC. If anyone can help me id greatly appreciate it!
