Thanks for your quick reply. Yes, the NANO3 has the blue power LED ON.
I have the jumper on the USBtinyISP on so it is powered by the prog'r.
Also, I tried powering the NANO3 via the USB port. Windows recognizes it on COM3.
When I try this way, I remove the jumper on the prog'r.
So, you suspect the problem is on the NANO3?
Thanks,
