@lj-keus if you turn off apparmor
sudo /etc/init.d/apparmor stop sudo /etc/init.d/apparmor teardown does that fix the issue for you? (Please re-enable apparmor immediately after the test using sudo /etc/init.d/apparmor start sudo stop libvirt-bin sudo start libvirt-bin ) -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu in Ubuntu. https://bugs.launchpad.net/bugs/1392504 Title: USB Passthrough is not working anymore To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1392504/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
