Could not configure port: (25, 'Inappropriate ioctl for device') (Linux Mint)

newageretronerd · July 22, 2023, 5:19am

I’m using VSCode on Linux Mint to upload some firmware to a Wemos d1 mini. I’m to a point where I’m directing to the right serial port but when I’m attempting the upload I get the following message:

Looking for upload port...

What happens if you comment out the port from platformio.ini? PlatformIO is pretty good at finding the correct port on its own.

I use Linux Mint too, and somewhere I have a D1 Mini. I don’t recall having specified a port.

Also, /dev/bus/usb/001/007 – I’ve never specified a port that way before. I’m not saying it’s incorrect, but usually it’s something like /dev/ttyUSB0 or similar. Maybe /dev/ttyACM0.

Cheers,
Norm.

I have tried setting it to auto (the port isn’t specefied within the platformio.ini but rather the enviroment) and it tells me to set upload port/install 99 udev which is already installed.

As best as I can tell that’s where the board is read on my device. I can’t see any file such as ttySUSB0 or the like. The device definitely at least reads into /dev/bus/usb/… since it adds a id file such as 007 when plugged inand removes it when unplugged.

Not sure if this problem is coming up because I have the extension working weird. Basically I had an issue where I wasn’t seeing I had python3-venv for installation but I got the extension to install by reinstalling VSCode with a flatpack. So not sure if that means anything, I’m newer to working with this stuff.

Thanks

Interesting.

I’ve just dug out my D1 Mini and plugged it into USB while dmesg --follow was running in a terminal. I got this in the log:

  229.322827] usb 3-2: new full-speed USB device number 8 using xhci_hcd
[  229.472537] usb 3-2: New USB device found, idVendor=1a86, idProduct=7523, bcdDevice= 2.64

[  229.476769] usb 3-2: ch341-uart converter now attached to ttyUSB0

From the last line, I can see it’s connected to /dev/ttyUSB0.

I have the famous blink sketch created with the following platformio.ini file:

[env:d1_mini]
platform = espressif8266
board = d1_mini
framework = arduino

And this source:

#include "Arduino.h"

void setup() {
    pinMode(LED_BUILTIN, OUTPUT);
}


void loop() {
    // LED: On = LOW, Off = HIGH.
    // It's because the LED is sinking current as
    // opposed to sourcing it.
    digitalWrite(LED_BUILTIN, LOW);
    delay(1000);
    digitalWrite(LED_BUILTIN, HIGH);
    delay(2000);
}

Uploading this simple blink sketch gives me the following, and you can see it autodetected the correct port:

My D1 Mini came from AZ Delivery, in Germany, before Brexit when we used to be able to order stuff from Europe, and has a CH340G chip for USB communications. Maybe your’s has a different chip which might mean that your port will be /dev/ttyACM0?

The /dev/bus/usb/nnn/yyy port name will change according to whatever (other) USB devices you have attached. I would delete the environment variable that defines it, just in case. Also, unplug the board, open a terminal and run dmesg --follow , wait for text to stop scrolling and press RETURN a couple of times, then plug in the D1 Mini. See if that gives any clues.

Cheers,
Norm.

Ok so from the looks of it my device might not be connecting correctly to my PC. While running dmesg --follow I also tried unplugging and replugging in my device. When it said the usb cord might be bad I switched to another cord but that didn’t seem to change much. This is the following output I got:

I’m not entirely sure what to make of this tbh. It appears the board might be disconnecting from ttySUSB0 immediately which is odd. Definitely could use some help parsing this.
Thanks.

Ok, I have the solution.

This is your problem:

[  592.823315] input: BRLTTY 6.4 Linux Screen Driver Keyboard as /devices/virtual/input/input14
[  592.833866] usb 1-1.1: usbfs: interface 0 claimed by ch341 while 'brltty' sets config #1
[  592.836854] ch341-uart ttyUSB0: ch341-uart converter now disconnected from ttyUSB0
[  592.836886] ch341 1-1.1:1.0: device disconnected

Linux Mint, by default, installs a Braille terminal, see https://brltty.app/ for details of what it is, which grabs ttyUSB0. I had this very same problem when I first upgraded to Mint 21. If you don’t need brltty, then get rid of it as follows:

sudo apt remove brltty

If you do need it, then /etc/brltty.conf might have an option to allow you to pick a device, to stop it hijacking /dev/ttyUSB0.

Full details here, https://lynxbee.com/solved-brltty-usb-com-port-gets-immediately-disconnected/.

HTH

Cheers,
Norm.

Thanks so much! I didn’t even realize that’s why it wasn’t connecting normally.

Dmesg is your friend for these things!

I have just suffered from the same thing! The VSCode PlatformIO extension tried to upgrade to 6.1.9, but stalled telling me it couldn’t find a working Python 3.6+ interpreter.

I eventually solved it. python -m venv --help worked fine, but python -m ensurepip --help said there was no ensurepip module. So:

python3 --version
Python 3.16.6

sudo apt search python3.13 | grep -e ensurepip -e venv`
p   python3.10-venv                           - Interactive high-level object-oriented language (pyv
p   python3.10-venv:i386                      - Interactive high-level object-oriented language (pyv
v   python3.10-venv:any                       -  

sudo apt install python3.10-venv

Now python3 -m ensurepip --help worked. On re-opening VSCode, the upgrade started again, and completed.

I’m not a fan of flatpacks, I had a few troubles with them a while back. I prefer the native apps, wherever possible.

HTH

Cheers,
Norm.

Thanks, I’ll try getting the package version to work. The fun thing is I finally got the software figured out for this project but now it appears I messed up the hardware. I already emailed the guy who makes the kit though since he’d probably know best what I either broke or just messed up with the hardware.
Again though thanks for all the help. This is teaching me a lot about working with software like this.
