After disconnecting the PICO, it will not be randomly cut off. It can always be connected to EBB36 ~/klippy-env/bin/python ~/klipper/scripts/canbus_query.py can0 Total 1 uuids found

I have similiar problem with my CB1 plugged into Manta M8P. The U2C gets disconnected after pluging in the BTT HDMI5 to the USB port. Everything works after I reboot the system.

I also have a similar issue with my CB1 / Manta E3EZ, the board randomly loses connection with the MCU. During my testing I have found that having the HDMI 5 connected is what is causing the issue. Not sure if it is the CB1 or HDMI5 that is at fault, but reading everyone's comments I am leaning more towards CB1.

I think this has something to do with issue #125

I think this is not a problem. After the Klipper is successful in the CanBus, it will not be displayed in the display "Total" through the command line, because the Klipper has been successfully connected to the device. It's okay.
