How do you know which physical port the something is plugged into without looking at the device in real life? On my mithrax (M123 kernel 5.15) in front of me, I see this identical setup if something is physically plugged into the **left**-hand port.

Can you verify if setting the usb mode works? Maybe: `cat /sys/class/typec/port0/usb-role-switch/role`. If it says `none` you have the problem I do. If it says `device`, maybe there is something different with my mithrax device. Verify the other port : `cat /sys/class/typec/port1/usb-role-switch/role`, my hunch is that it will say `device`.

In other words, mithrax is enumerating the left-hand port as port**0** because it happens to be first in the ACPI table.  But the `physical_location/panel` is saying it should be port**1**.
