Hi, just taken delivery of a CAM008 (night vision camera module) and connected it to a RPi 2 Model B with a fresh install of Bullseye.  
When I issue the command libcamera-hello I get:

libEGL warning: DRI2: failed to authenticate  
Made X/EGL preview window  
[0:16:27.787362271] [1173] INFO Camera camera\_manager.cpp:293 libcamera v0.0.0+3406-e96d0201  
[0:16:27.845399952] [1186] ERROR CameraSensor camera\_sensor.cpp:551 ‘ov5647 10-0036’: Camera sensor does not support test pattern modes.  
[0:16:27.947689265] [1186] INFO RPI raspberrypi.cpp:1326 Registered camera /base/soc/i2c0mux/i2c@1/ov5647@36 to Unicam device /dev/media3 and ISP device /dev/media0

I get the same error if I try a standard RPi camera (v2)

I presume I’m doing something really basic incorrectly…?

PS Works fine under older OS…

Thanks,

Andrew

This may help? [Use Picamera with Raspberry Pi OS Bullseye](https://youtu.be/E7KPSc_Xr24)

Forgot about that option - works a treat!
