Glad that you have a better understanding now.
Using the digital I/O from your MOTU with the H9k will definitely be an easier way to set it up. You won't need to do any of the above USB sample rate steps, you will just send audio to/from the appropriate I/O on the audio interface and H9k and thats pretty much it.
Another thing to clarify; the H9k does not connect to Emote via USB. The USB connection is only for using the H9k USB audio feature. Emote can connect to your H9k via a direct ethernet connection, a networked connection using an ethernet cable from your router, or wirelessly using the included Wi-Fi dongle. If your rackmounted gear is not near your computer, the easiest way to connect would probably be with the Wi-Fi dongle.
