Qubes installation without exposing to USB controllers

[Dann Swing]

How to add "rd.qubes.hide_all_usb" option before starting Qubes 3.2 installation from DVD?

I suppose that, before Qubes installation you may disable USB controllers in BIOS and check it on any Linux distribution typing lspci or on Windows in device manager. After installation you must add "rd.qubes.hide_all_usb" option and after that enable USB controllers in BIOS.
