We are in a project where we have to feed an OAK PRO D POE s2 with a 5V source, so we use the M8 connector with USB and use data via ethernet.
This doesn't work for us because when we run a detection, the OAK D resets, but it does work when we just run a script to watch video it works correctly when powered by usb.
We don't understand what the error is.
We use this architecture to not use a POE source and a 5v source for our raspberry host.
