Cannot use the code in my extension

[karelbilek]

If I want to use the code in u2f extension in my own extension, I cannot get through this because of the manifest.

There were warnings when trying to install this extension:

• 'hid' is only allowed for packaged apps, but this is a extension.
• 'usb' is only allowed for packaged apps, but this is a extension.
• 'usbDevices' is only allowed for packaged apps, but this is a extension.

I cannot use it in an app though, because google is retiring Chrome Apps and will not allow new apps soon.

So it seems there is no solution to this and I cannot use the hid API in non-blessed Chrome extension?
