This seems to indicate that we got the ANSI/ISO numbers wrong in a
recent patch. IIRC, there was doubt already when the patch was
applied (Linus T CC'd). Most likely the right patch is this:

        .match_flags = (USB_DEVICE_ID_MATCH_DEVICE |            \

Brad, Linus, does the above patch work for you as well as for Ian?

Thanks,
Henrik
