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. ladis -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
