They are adjacent to the values that are allocated in the 1.12 spec; the USB web site describes a process for asking for new fields to be defined in that space. Whether they are being used properly, is what I'd like to ensure; I have a comment or two in the report data structure source I have that would give me insight as to whether they are using them correctly. If not, I want to complain at them... > > I can go dig through any pre-released specs that are availble if you > think it is something that is being used properly. > That would be greatly appreciated.
