USB Port Not Showing Up In Arduino - Feather Huzzah ESP2866

Support Adafruit
1

When the device is plugged in, the USB port isn’t available in Arduino - only the Bluetooth ports show as you can see here.

Have done some googling and it seems this is happening to a few people. Not sure if it’s a macOS issue or problem with the board. Have tied a few suggested fixes (installing CH34x drivers, resetting the SMC etc)

Any help would be great!

Hi Nick,

Oh no, sorry to hear that. I’ve just done a bit of a dive into some causes for the issue and it looks like there’s a few things it could be. All of the things I would try to do have been documented in this support post on the Adafruit forums: https://forums.adafruit.com/viewtopic.php?f=22&t=91868

I would try every suggested fix on there, and particularly check your system devices to see if it’s been recognized as a device by your operating system.

As mentioned in the following support post, have you reflashed your device firmware? https://learn.adafruit.com/adafruit-feather-huzzah-esp8266/using-arduino-ide

Solved the issue. Just had to re-install the driver :slightly_smiling_face:

Awesome, glad to hear it. Sometimes it helps to just voice the problem to someone else :slight_smile: What projects do you have in mind for the board?
