No, we need to tell users if we're deferring since there's no guarantee that the device blocking registration is ever going to be loaded - we need to let the user know why the device isn't appearing so that they can diagnose problems. Yes, it's noisy and ideally we'd have something more efficient than deferred probe but there we are. --/qIPZgKzMPM+y5U5 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBAgAGBQJUhx/bAAoJECTWi3JdVIfQ29MH/2kydy0SpwwfeK5eoWSo3CQL LQtN6hcr6+BXkHP1bWGzoKlsFMxJH21xXMZt6mTe3GutqQdOPr4brbm7TU3arQTm J2KBQGncHMhBEFO3NhYVuDqEQrEkf/0jyQdKqrs0+KA5pU9qQeuyu6MX0LhmKlcY jXYd03/5+Uy79pt6o0JkDtlCK0i6AL5spUulNHFsPDDiNrN5Vr73890Aw2kWD1lb C0C4a9hW1g/kbRqbob8//xfBvqwcpx8qt+QKTuBgVM9c89v7ndGZlrTwBuZCBXHQ gtAPRx7KoDcA4lK6lyOQ2lTL0qb8gYqs7FEfAjgV17Ctfldd4bQBVCMBairZnHU= =l2Qh -----END PGP SIGNATURE----- --/qIPZgKzMPM+y5U5--
