I'm using osx Sierra and adafruit feather esp8266. I had them working fine a few months ago, but recently the usb port was not showing up in the arduino IDE (version 1.8.0).
I couldn't get it to work for ages until a few days when I reinstalled the usb driver https://www.silabs.com/products/develop ... cp-drivers
And it worked fine.
Just opened the arduino IDE again after a few days and it's not recognising it again
Anyone else ha similar problems...It's really frustrating and I'm hoping to get some stability so I can develop projects etc.
Thanks in advance!
