Mike Woods,
? ? Thank you for the answer. It was the USB A to mini B cable. It must have been like the one you described as for power only.?
I tried a thicker cable and the serial port appeared and the new firmware loaded successfully. i also downloaded the ch340 driver.
My first contact was from So. Cal to?Hawaii on 40m SSB so all is good. I learned something about cables tonight. 73 Mike KF6KXG
