Message:

Better virtual USB HID; USB-virt rewritten

The new virtual USB HID is easily extensible with new interfaces that
might provide different report descriptors.

The virtual host controller was completely rewritten together
with the libusbvirt.

The documentation is missing and the code would deserver some refactoring.
That will appear later.
