[MCU] Connection only when Octopus powered via USB and no Cables plugged into the Octopus.

-Octopus v1.1 -Pie 3a+ -RatOs Hello, My issue is the my RatOS instance only connecting to the MCU via USB when the Octopus 1.1 has no Cables plugged into it except the USB cable and the USB-Power Jumper beeing jumped. Then the Raspy also doesnt generate a /serial/by-id directory. There also is no lsusb when the Octopus has all wiring plugged in, BUT if ONLY the usb cable and Power jumper are plugged in, The lsusb shows the board. Ive read up on the klipper forum and Cant pin point what the issue is. Maybe the Pi not generating a /serial directory, when its connected to the fully plugged in Octopus board, but i cant figure out why that would be the case. Maybe some of you have an insight to help me along 😦

The Setup assistend said it connected and .cur. It connects, but only if no cables except the usb cable to the pi is connected and the power jumper set
