Hi Brian It is pretty weird that the driver is unmmaped without any extra message on dmesg. What distro are you using? Are you using any kind of virtualization scheme? Could you try the following? 1) Reboot 2) sudo dmesg -c > dmesg.1 3) v4l2-ctl --list-devices 4) sudo dmesg -c > dmesg.2 5) find /sys/devices/pci0000:00/0000:00:1d.2/0000:04:00.0 6) for a in $(find /sys/devices/ | grep authorized); do echo $a; cat $a; done Then share the output of the commands + dmesg.1 and dmesg.2 I hope to see some disconnect message, or the device being unauthorized, otherwise I am a bit out of ideas :) Thanks On Mon, 26 Sept 2022 at 17:34, Brian Morrison <bdm@xxxxxxxxxxxxx> wrote: > > On Mon, 26 Sep 2022 09:22:12 +0200 > Ricardo Ribalda <ribalda@xxxxxxxxxxxx>
