After a clean install of RaspberrypiOS (bullseye) on my Zero 1 WH, I have installed the UUgear software and then mounted the Zero2go.
After that I tried to use the camera 'libcamera-vid --list-cameras' gives "No cameras available!"
I know everything else is ok, because I used the same camera and the same raspi-board in a previous install.
Looking for problems I found the log file uwi.log. It repeats endlessly these lines:
Running command: /home/pi/uwi/websocketd --address=raspberrypi --port=8000 --staticdir=/home/pi/uwi /home/pi/uwi/messanger.sh

Of course, in my network the hostname 'raspberrypi' does not exist.
How to configure the server / ip /port is not really mentioned in the manual that I downloaded.
I also do not know if and how this is related to the camera problem.
If someone here knows more, please help!

First of all, this has nothing to do with your camera problem.
Those messages are all from UWI. You may change configurations in the uwi.conf file (in ~/uwi directory). You may run "./diagnose.sh" to automatically configure it, alternatively you may change the uwi.conf file like this:
...... host='0.0.0.0'; port=8000; web_socket_url='ws://'+window.location.hostname+':'+port+'/'; ......
More explaination about this configuration can be found here.

Thanks for the quick reply.
I want to follow this matter in a new thread (UWI not working), since it seems a different issue.
Will have another look at the camera later today.
