Problems Ethernet Extension Kit No cameras


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

Made X/EGL preview window
ERROR: *** no cameras available ***

help please
