Hello,
Yeah the link was broken before, but I already fixed it. I'm not
sure if my reply actually reached the mailing list (it accidentally
mixed up my sending adress). At least from the libcamera I got a
bounce, as I'm not a member.

Sophie, could you please share the `lsusb -v` output for the device (you
can limit it to a specific device with `-d VID:PID`), running as root
(e.g. with `sudo`) if possible ?
Note here that the idVendor and iManufacturer do not match. The
camera uses the same USB VID:PID as the Netchip "Gadget Zero", because
of course it does…
