    ng_ubt: Avoid attaching to several newer Intel controllers
    
    Like other Intel controllers, these require firmware to be loaded, and
    generic ng_ubt attach causes them to lock up until a power cycle.
    However, their firmware interface for querying version info and loading
    operational firmware is different from that implemented by ng_ubt_intel
    and iwmbtfw, so they are not usable yet.  Just disable attach for now to
    avoid stalls during USB device enumeration.
