Problems Ethernet Extension Kit No cameras

Hi,

I recently pruchased Arducam Enthernet Cable Extesion kit to use in my Pi 5 and Raspberry Camera HQ.

I followed the steps in starter kit and the camera works without the extension kit, but when I try to use the extension kit it shows:

libcamera-still -t 0
[0:00:33.743252739] [2350] INFO Camera camera_manager.cpp:284 libcamera v0.1.0+146-cff216fa-dirty (2023-12-05T10:19:54+00:00)
Made X/EGL preview window
ERROR: *** no cameras available ***

help please
