Your dmesg output does not contain any traces of a printer board.  
Make sure that the printer is properly powered and repeat the dmesg process according to [How-To Trouble-Shoot](https://klipper.discourse.group/t/how-to-trouble-shoot/6326#linux-dmesg-5)

Alternatively you can use the command `dmesg -w`, which will put dmesg into a monitoring mode, so that you see any changes live during disconnect / reconnecting the board
