Hi, I ran "udevadm monitor -kup" (this command does not terminate) and then "rmmod ipu3_cio2; modprobe ipu3_cio2", is that correct? Below is the output of udevadm after rmmod/modprobe. Thanks, Frédéric PS: maybe I should rather post to linux-media or linux-pci? ------------------------------ monitor will print the received events for: UDEV - the event which udev sends out after rule
