Adding the generic (and unsafe) line:
/dev/bus/usb/*/[0-9]* rw,
to /etc/apparmor.d/abstractions/libvirt-qemu and reloading profiles works for me so it seems the mechanism to dynamically add host devices to the apparmor profile has been bounced as well or not working anymore.
Just to confirm something is still not working for me:
$ sudo apt-cache showpkg libvirt-bin
Package: libvirt-bin
