    USB is "supposed" to have UTF-16 strings, but there's devices out there
    that have crazy stuff in them. And of course, anyone can put anything
    in the device string if they know how to write a bit of firmware, so we
    have to watch out for that. Hopefully we handle that properly in the
    usb_string() function in the kernel but review of it is always nice to

    Other than that, I don't know of any multi-byte strings in devices at
    the moment. I haven't seen the Thunderbolt specs though, so who knows
    what is coming next.

    Hope this helps,
