hmm... It was added by commit c02c4bb2058587d3c012ec08268fd93fdc654ae7
(USB: USB authentication states). According to the commit log (see
below) it was added for Wireless USB although that define isn't used
anywhere. At least USB_STATE_UNAUTHENTICATED is used by a couple files.
In any case, I don't think we can easily remove that define as it would
possibly break userland, so we need to provide a human-readable string
for it anyway.

[PATCH] USB: USB authentication states
Another hook needed for wireless USB: there are states associated with the
device authentication protocol. Wireless devices must authenticate using
the host system's keystore.
Note that wired connections could also use this authentication protocol, if
for no other reason than to support the most secure "simple" key exchange
protocols for wireless devices.
