Since KVM is running as root and the device is owned by root (and ACL gives 'user:rw' perms), I don't think the ACLs are to blame.
Could you try booting the system with 'apparmor=0' in the boot arguments? If it works then, then we know apparmor is somehow still causing this. --- Ubuntu Bug Squad volunteer triager http://wiki.ubuntu.com/BugSquad -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/787091 Title: Unable to use USB device in KVM quest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/787091/+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
