Read Log over usb serial on HA

[UsefulVid]

I have wifi connections problems with my ESP which runs ESPsomfy.
This may be more of a question and not feature request:
How can I read the serial log of my device? I can do it on my windows device with chrome browser but I need to run it 24/7 to reproduce the issue.
On my synology nas it seems to have a general problem with the usb port, it keeps crashing after start.
On the Rpi 4 with HA running it does not show any output:
