    I was able to fix the issue, though I’m not sure at all why it worked. When I have a microSD card in extra slot for datalogging the Mayfly board will not even power up. As soon as I pull the microSD card out the LED lights blink, the red one stays on and all is well. This seems to be a rather serious issue since the entire purpose of the mayfly is to log data. I can now communicate with the device/upload sketches. However, it seems my solution now leaves me with another problem…
