Comment 5 for bug 1514335

something strange also and maybe related:

- on my laptop under win10 64bits (but it was the same when it was under win7 64bits), all USB HID devices show up in the controller tree (mouse, keyboard, and so on)
- on my desktop PC under win7 64bits, I have no devices shown under controller except my MIDI controller. No HID (mouse, keyboard) and no bulk. My controller is even not shown as bulk despite it's also bulk compatible
