Summary: SELinux is preventing /usr/bin/qemu-kvm "ioctl" access on /dev/bus/usb/002/004. Detailed Description: [SELinux is in permissive mode. This access was not denied.] SELinux denied access requested by qemu-kvm. It is not expected that this access is required by qemu-kvm and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug report.

libvirt did not set the label on the device?
Apparentrly not. Not able to access the device.
