This is a custom device... If I understand USBTMC spec corectly, it is not
either "normal" message or vendor specific message, but both can happily
coexist, so I wouldn't let it depend on quirks. Once you are going to send
vendor specific message, you need to know how such a message looks like
anyway, so any quirk based magic is probably not going to help.
Also it seems both NI and IVI libs are using similar (selecting MsgID)
approach.
