Hello,
I got the camera
B0371
I am using Raspberry Pi Zero 2W
PRETTY_NAME=“Raspbian GNU/Linux 11 (bullseye)”
NAME=“Raspbian GNU/Linux”
VERSION_ID=“11”
VERSION=“11 (bullseye)”
VERSION_CODENAME=bullseye
ID=raspbian

Instruction: you have followed. (link/manual/etc.)
The /dev/viodeo0 appears in the OS. The libcamera-hello works.
The zbarcam complains about this camera:
$ zbarcam --verbose=32
