Issue Description

Hello,
We have bought 5 d450 depth modules, vision processor d4 v3s and rigid interposers. Whenever I connect the board to the laptop or jetson, in Windows or Ubuntu, it is never able to get any camera feed. I have tried realsense-ros, realsense viewer in both windows and ubuntu, none seem to be able to recognize it. When i connect just the vision processor it shows it as a tester so i guess it is working. In windows it shows that the device has malfunctioned.

Any help would be appreciated
Thank you

Hi @Ojas-Chanakya131 It sounds as though the rigid interposer might not be functioning. The camera identifies as D405i Tester when the depth module is not connected to the interposer, so only the Vision Processor D4 board is activated.

Have you connected the D450 to the 50-pin connector on top of the long side of the board and not the connector on the short side?
