Support USB API

[MarcAntoine-Arnaud]

Is it possible to support Web USB API ?
Examples of required features can be found here: https://developers.google.com/web/updates/2016/03/access-usb-devices-on-the-web

Only chrome as implemented that API, but it can be great to expose it.

Thanks for the report! We currently support stage 3 and above proposals and we support them by copying in the official WebIDL file into our webidl folder, do you know what stage this proposal is at and where it's WebIDL can be found?

Thanks for the reply.
And I learn something, I know nothing about IDL, but right now more ;-)

I have found https://wicg.github.io/webusb/#idl-index (very recent update...)

Do you think it can be safe to add that one:

I'm going to close this in favor of #1950 which is a general strategy of how to support unstable WebIDL files.
