May 22, 2017 · udev has never been meant to be any big database of all information about all devices in the system and it wasn’t designed to provide any high-level events. So using other mechanisms for sharing the information about storage related actions and changes could be a great step forward for all tools, daemons,… requiring such data. - Aug 22, 2019 · So, the cause of the problem is not the kernel. The actual line in the above udev file that causes the problems: KERNEL=="sr[0-9]*", ENV{ID_CDROM}="1" So, I am thinking that this line triggers something else, perhaps another udev rule, that is interfering with usage of the optical drive.

Working solution: udev. Udev is a device manager, which is responsible for managing /dev/ directory and giving drives names ("nodes") like /dev/sda when they are inserted.

Feb 09, 2017 · The daemon searches configured rules to match the event with a rule to identify the device. The kernel usually assigns a name that is neither meaningful nor repeatable, so udev usually assigns a more meaningful and consistent name. The udev rules are in /usr/lib/udev/rules.d, with additional local rules in /etc/udev/rules.d.
