WebUSB API issue

[drom]

I am trying to use WebUSB API and getting the error.

code: https://github.com/drom/jsdr/blob/master/experiments/WebUSB/src/app.js

My platform:

• nwjs 0.18.3
• Linux 4.8.4-1-default (x64)

Error:

Does Chrome 54 working in the same system?

[drom]

Yes, it does works in chromium 54.0.2840.71 with flag: --enable-experimental-web-platform-features
on the same machine.

Upstream disabled this feature for Chrome Apps: https://bugs.chromium.org/p/chromium/issues/detail?id=610880

We'll enable it because we use a different security model.

This is fixed in git and will be available in the next nightly build.
