Hi I cant find an answer to my query so hopefully someone can help me.

I have been playing with funcard programming tonight...

I am trying to use my USB reader with the nagra 3 software as recommended by your forums. I program a funcard using the infinity software and then set the nagra edit to COM3 (hope this is correct) even though the interface is USB. The card is not detected so does my problem lie with an invalid ATR or is the ATMEGA related? "unsupported card type" is the error even if I try and load a known working card.

Any help would be much appreciated...
