IDE cannot find the USB connection.

Development Tools IDE 1.x
1

Manjaro linux.
Arduino 1.8.12
Example Sketch is Blink

It works if I use a Nodemcu board but I get this error when I use a Feather Huzzah.
I tried adjusting the rwx, properties on the ttyUSB0, port but it didn't help.
I tried going back to ver 2.5 of the board but still no love.

esptool.py v2.8
Serial port /dev/ttyUSB0

Do you see a new port appear under the Arduino IDE's Tools > Port menu after connecting the USB cable of the Huzzah to your computer?

Note that you need to close and reopen the Arduino IDE's Tools menu to refresh the Tools > Port menu.

Yes, IDE shows the port to be connected. It's when the compile is finished and it begins to do the upload that the error occurs.

Something else I found and maybe you can pass it along is this.
The blink example will work when I remove the tx and rx connections to it.
They really weren't needed, I just happened to leave them in for another sketch.
Take them out and blink works, put them in and it errors.
I have only tried this twice so I will need to verify it once again.

Bye for now.

Are you saying you have something connected to the RX and TX pins on the Adafruit Feather Huzzah board? Those pins are used for uploading sketched to the board, so connecting anything to them can cause uploads to fail.

Yes re the rx and tx pins.
From the feather they connect to an Adafruit GPS component, part ADA 746

You'll either need to disconnect the GPS module every time you want to upload, or else use a software serial library to create a serial port on some other pins on the Adafruit Feather Huzzah, and connect the GPS module to those pins instead.

Thank you again Pert, this was the answer. Upon further reading of the sketch I found some comments re connecting the rx and tx of the GPS. And as you said it was not to the Feather.
