FT-450D Digimodes revisited

I'd had a few questions on how I connect the computer to the FT-450D when using digimodes (or even just controlling it with a program like Ham Radio Deluxe) and decided to do a block diagram of how I achieve this.
This diagram is a full picture of the station layout so you can see how everything hooks together. Feel free to use it for the basis for your own datamodes operation.
In case you are wondering why I have 2 ATUs, one is in the shack for tuning the Diamond 2000 when it is switched into circuit and the other is outside at the feed point of the 9:1 UNUN end fed antenna.

Physically I have two USB hubs in circuit. One of them has USB sockets arranged side by side and the other in a vertical column pattern. The USB deices that plug into them can't go into one hub as they foul each other. Either they are too wide or too thick to have them all in one hub. So having two enables full flexibility and physical room. The diagram only shows one hub for clarity.
