I'm afraid that these steps didn't help for me. I made the changes indicated in: https://bugzilla.suse.com/attachment.cgi?id=873962&action=diff and in: https://bugzilla.suse.com/attachment.cgi?id=873963&action=diff with the change from 660 to 650 in lines 50 and 52, and also ran /usr/lib/virtualbox/vboxdrv.sh restart On reboot, I still get a locked /dev/vboxusb directory, and the user enumeration error on firing up the Windows VM. I'm on snapshot 20240329.
