no union descriptor, or (b) the union descriptor is misplaced on data
interface instead of communications interface.
So in the NetBSD code again, that would be why umodem_get_caps()
returns -1 and is the one ruining the match in umodem_match()...
But we also have a UQ_NO_UNION_NRM flag available (umodem_get_caps()
in umodem_common.c). I would try to apply this for the Conexant
