Can anyone help me and possibly paste some links how to get started?

Maybe user had no rights to access usb ports.
Searching for the combination ’ usb rights user ’ may help you.

Unfortunately, after doing the action, I still don’t have the last option as read / write:

ls -al /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 04-25 11:55 /dev/ttyUSB0

sudo adduser $USER dialout

Logout or reboot after

The user “tomasz” is already a member of the “dialout” group.

Check if you use a good USB cable. Try another one.

I was able to flash ESP with this cable, so I don’t think it is broken.

So I conclude that ESP works and communication is there too.

Sorry to post under the post, but I changed the software and it didn’t change anything.

Different cable - no difference

Do a ‘lsusb’ command in a monitor window.
First WITHOUT the node and right after that WITH the node.

The difference is the usb chip in the node.
Maybe you need another driver for that chip ?

It’s also possible you did not follow the instructions like explained here.

I had difficulties on an older linux laptop to get the meshtastic client running well.
The problem was with python and had to install several python stuff before it worked.
I cannot remember exact what I had to install but every time I got some clues from error-messages in the terminal window about what was missing.

There was no module on one cable, on the other (what I was uploading the firmware):

Bus 001 Device 009: ID 1a86:7523 QinHeng Electronics CH340 serial converter

So the cable is OK.
I am also convinced that it is the fault of softwarre, but I do not know python so that I know what is wrong with it.
