Hello, I am experiencing the same problem -I think. husb: open device 2.3 /dev/bus/usb/002/003: Operation not permitted root@zentyal:/var/lib/zentyal/machines/wg# chmod 777 /dev/bus/usb/002/003
root@zentyal:/var/lib/zentyal/machines/wg# lsof /dev/bus/usb/001/002 Unfortunately, the fix does not work for me: umount -a -t cgroup error: Failed to create domain from /var/lib/zentyal/machines/wg/domain.xml error: internal error Unable to find cgroup for wg Please let me know, if this is a different issue/and/or I should open a new bug.
