No serial USB port for mac in Arduino IDE

by jwbacn on Sat Jun 29, 2019 10:55 pm

I have an Arduino Trinket 5v I am trying to connect to my computer via USB. When I click Tools>Port there are no USB options listed. It shows multiple /dev/cu.XXXX options which are bluetooth related.

I have tried on my 2016 Macbook Pro Mojave with no luck, and have looked on StackExchange and have tried installing CH 34X drivers to no avail. I have also tried on a 2013 Macbook Air Mojave and it doesn't work.

I have downloaded the trinket libraries and have selected the board as 'Pro Tinket 5V/16MHz (FTDI)' although I don't think this is related to the port. I have tried multiple cables and am using one that *does connect* to an Adafruit Pyportal.

The tutorial I was following says no drivers required on the mac. Thanks for your help!

The Pro Trinket doesn't register as a Serial Port in the Arduino IDE.

The board doesn't have any real USB hardware, the bootloader just emulates a low-speed USB connection long enough to upload firmware. The details are explained in the tutorial:

Hey Mike thanks for your reply. I'm still confused. Can I use the microUSB at all? Or do I need to purchase something else like this?

https://www.adafruit.com/product/954

The tutorial didn't list that as a necessary part.

Also I'm using Arduino 1.8.9 - is the bug referenced in your link squashed in this newer version?

There's nothing referenced in the tutorial about this (https://learn.adafruit.com/bike-wheel-p ... y/overview).

You can program the Pro Trinket through the micro-USB jack without using an external USB-to-Serial converter. You just have to reset the board manually to force the bootloader to launch and start emulating a USB connection when the IDE is ready to upload the firmware.

It's all covered on the tutorial page linked above.

Same issue on my Mac. Same Mac that he's been used to program 2 5v Pro Trinkets in the past. Cable is good. The IDE just can't find it.

avrdude done. Thank you.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
