Ok scrap that last statement.
The two items I purchased arrived today,
nice enough but they do not offer any communication over either of the USB ports so they only display on the screen itself.
I guess I misunderstood the line "Communication function: Yes"
for reference this is the controller it contains.

I'll have a probe around later to see if perhaps there is some debug lines that have any related output.
I suspect if some smart cookie was to make something similar, based on an atmel, with open source firmware compatible with the Arduino environment, they would become rich pretty quick.
