Need help with Serial Port Settings to connect

What is the problem?

I can't get octoprint to connect with my printer and the dmesg output does not show the needed code in this help article - OctoPrint can't connect to my printer

What did you already try to solve it?

I followed all steps in OctoPrint can't connect to my printer and it said to set up a Get Help ticket if it did not work.

Have you tried running in safe mode?

Yes, that did not fix the issue

Did running in safe mode solve the problem?

no

Hello @Brian_Luley !

Also: Have you checkt the USB cable for proper data connection?

I dont see any serial port option but 'AUTO' unfortunately and they isnt selectable.

Here is the systeminfo though -

Hi @Ewald_Ikemann , thank you for the help. I included the systeminfo file below. Does that help?
How do I check if the USB cable is working? I have already completed an update with it.

Ultimately, I am trying to connect my printer to the comp wirelessly through the Raspberry Pi I have installed with OctoPrint
