on my windows 7 pc, whenever I try to progrsm my Ard Micro (not PRO), as son as I start to send the code to the Micro, the comm port disconnects and then a few seconds later it reconnects. Hence I can not get code to the Ardunio.
Actually, you got it confused with the "Mini" or Pro Mini, which requires an external USB adaptor.
But this behaviour of the micro/ Pro Micro is common, I do not recall the answer (which is why I did not offer it as such) and have yet to get one to function myself!
I may have more luck with the latest IDE which handles itinerant ports better.
