This article says that the USB-IF "is going a step further" with this cryptographic authentication, which isn't quite right. The 'I trust this device' system allows confirming that you trust the device. This crypto confirms that the USB-IF trust the device (and presumably all they are asserting is that the device conforms to standard). It's an interesting idea, and not a bad one. That's assuming the certificate system is sound which I remain sceptical of until I know more, given the normal issues with managing a single unrevocable private certificate.
