On the 20732A0, I download the code, remove the USB, from the mini-switches on the board I flip the two switches so data can be displayed on the console. I replace the USB, then I can see output, and input keystrokes.
On the 20732A1, I follow the exact same steps, but there is no output and I can't input data; But if I flip the switches back (without disconnecting the USB), I see output, put I can't input anything?
