Message:

Virtual USB layer rewritten

Major changes include

• IPC sends whole transfers (not transactions)
• separate transfer queues for each device in host controller
• possibility to return NAK from virtual device (handled by HC)
• better implementation of callbacks for non-zero endpoints

Still missing

• communication for some transfer types (bulk)
• face-lift
• documentation
