Camera Multiplexers

Hi all!
I recently bought an “Arducam Multi Camera Adapter Doubleplexer Stereo Module V2 for Raspberry” and I’m having some difficulty.

I’m using the Raspberry 3 b+.

I tested the cameras directly in the raspberry and they worked fine.

I also enabled the I2C and camera in the config file.
My cameras are the ov5647 5MP.
I aways get the same error:

Choose camera A
libEGL warning: DRI2: failed to authenticate
[71:43:44.033211325] [22003] INFO Camera camera_manager.cpp:293 libcamera v0.0.0
ERROR: *** no cameras available ***
Choose Camera B
libEGL warning: DRI2: failed to authenticate
[71:43:44.585128522] [22017] INFO Camera camera_manager.cpp:293 libcamera v0.0.0
ERROR: *** no cameras available ***
Test OK

Anyone can help? What I’m doing wrong?

Can somebody help me?
