The syslog output looks like its from the Host not the guest? What does the libvirtd log say for the guest...typically at /var/log/libvirt/qemu/XXX (XXX being the name of the guest).
There are 2 separate issues/related in this thread, first being USB attachment to guests not working which is believed ownership related hence my *workaround* in post #23. The second is about how the USB device is re-atrached to the Host once the guest has been destroyed...this is what the syslog/dmesg outputs are about and why Serge has renamed the bug report.
