nope. that rules out the IC1T and the jz4775 CPU cards. not gonna
happen. It is always to balance between requirements. If this CPU card forces Miguel to add $4 IC, that what's the benefit of $2 SoC? In fact probably his product will be useless with IC1T? If I was him, I would say that such cards are not supported in his product and put an end to this. Instead of searching for expensive hubs and changing the base board to support this - just to be able to conform to all options and support card that just can't be used there because of other limitations. Is it so that any EOMA based product (like his console) should run with any EOMA card (I mean to be able to run with minimum supported feature set of the standard)? Is it allowed to have a product that requires some of optional features to be present? If this is out of the scope of the discussion, just ignore it. Personally I have some other problems with EOMA idea so I had to switch my design to other form factor - so I don't "deserve" answer. Just trying to be helpful.

don't worry about it. really.
1st USB ---> USB5434B-JZX --> USB Host 3.0 --> USB WIFI --> USB BT --> USB Audio
2nd USB ---> STM32F072
What about this?
The USB5434B-JZX seems to supports 3.0, 2.0 and 1.1.
have you also added in a PMIC for supporting the USB3 current requirements?

$4 from a US-based company is a hell of a lot more than $1 for an extremely popular FE1.1.
honestly the extra power requirements and the cost i would say are simply not worth the hassle.
