No connection BTT SKR2.0

What is the problem?

I'm trying to connect my octopi (which used to work great) to my new Bigtreetech SKR 2.0 board. I've used four different USB cables without success. I've seen many people frustrated trying to connect to these boards, but I've also heard many more have success. I'd like to be one of the success stories.

What did you already try to solve it?

Multiple USB cables.

Have you tried running in safe mode?

Yes

Did running in safe mode solve the problem?

No

RE

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible

1.71,Version 0.18.0, running on Raspberry Pi 3 Model B Rev 1.2, Artillery Sidewinder with BTT SKR2 board and TFT35 v3. bugfix 2.0.x, windows 11.

I really wonder what the challenge is with those boards. Is there anything fancy connected to it, display or so?

Please ssh into your raspi and take a look at the kernel messages:

  • sudo dmesg -w
    (this prints out the current content of the message buffer and then waits/keeps printing them once new messages appear)
  • now unplug the printer, then plug it in again
  • maybe try variants like printer powered or not powered while plugging.
  • monitor the messages in the console.
  • Copy/Paste the tail with the usb-related lines here as text

tried sudo dmesg -w. got info but after it displays the messages, it stops and displays no more. Started pi, logged into the system, attempted to connect to printer. ssh and retrieved messages. no matter what I do with the pi, I get no more messages. tried to copy ssh text but not having much luck. Thanks

the kernel seems to see it though:

and a few lines down:

Are you sure the serial port settings in Marlin are correct? I don't know what the correct ones are (would have to ask Marlin people) but if the port is being seen by the OS but not responding to OctoPrint's hello attempts, there may be something in the firmware.

What is configured for the serial ports now in your Marlin config?
