Hello @hugoM , sorry for the inconvenience. This would either be that the camera is not supported by library (so using old library) or that it's physically not connected (very rarely happens while shipping).
So I would first try updating library - running python3 -mpip install depthai -U
, and if you keep getting this error, please send us an email to support@luxonis.com so we can either send you a replacement or guide you on how to re-attach the camera (opening the enclosure, and reattaching the connector).
Thanks, Erik
