[BUG] {Failed to find device after booting, error message: X_LINK_DEVICE_NOT_FOUND POE Bridged Connection on Seeed ReComputer}

Check if issue already exists

• I have read thru all 43 issues mentioning X_LINK_DEVICE_NOT_FOUND but none have addressed the specific problem I am having.

Describe the bug When I use a bridge connection with network on eth0 and Oak-d POE on eth1 the camera gets assigned IP address 192.168.93.113 and br0 gets IP address 192.168.93.106. I can connect fine using device_manager.py but depthai_demo.py, depthai-vewer, and all the experiment examples fail after I hear the autofocus on the camera click with Failed to connect to device, error message: X_LINK_DEVICE_NOT_FOUND. These programs all work when I setup local link and when I use a POE injector and plug it directly into the switch. However I must have the camera available to all endpoints on the network, not just locally and it must go thru the seeed studio recomputer.

Minimal Reproducible Example

1. disable all network connections in the gui
2. Make entries in /etc/udev/rules.d/10-persistent-net.rules and /etc/systemd/network/70-* if necessary.
3. Disable existing connections if necessary nmcli con delete 4.Create a bridge nmcli con add type bridge con-name br0 ifname br0
4. Add workers nmcli con add type ethernet con-name eth0-slave ifname eth0 master br0 nmcli con add type ethernet con-name eth1-slave ifname eth1 master br0
5. enable nmcli con up br0

Expected behavior Network camera should be available thru the network.

Hi @hellkrusher , how are you powering the device? Could you share some pics? Seems very much like power issue, perhaps relevant docs here: https://docs.luxonis.com/hardware/platform/deploy/powering-poe/#Powering%20OAK%20PoE%20devices-Powering%20from%20M8%20connector
