Anyway, back on topic... I edited the specs at
http://rhombus-tech.net/community_ideas/carrier_board/
<http://rhombus-tech.net/community_ideas/carrier_board/?updated>  to include
a second USB2 Hub slaved to the 4th USB3 Port With the EOMA's singular USB
Host routed to the USB3 IC. It is added with a caveat though and should be
noted that everything is subject to change.  I would prefer to use the
Microchip products, direct from them as they're readily available and I can
literally drive to the warehouse and pickup everything in 20 minutes from
here. I've been having a hard time finding a source of the FE1.1 in the US,
but just spoke to a Supplier in China, and he said they could source 500
FE1.1 for .45c a piece, not bad. 

 

Either way, It will bring the total to 3x USB3 Ports, and 2 Internal USB2
Headers (10pin).

 

Right now I am pricing things based not only on cost, but how readily
available the components are, and as local as possible. I've been lucky so
far in that I have been able to source MOST components at near China prices,
but without having to actually get the parts directly from China. 

 

 

The only other items I would like to add for my wishlist are:

1.   a provision for either an onboard battery or a header (or pinholes for
user mounted header) to connect an external battery to keep the RTC powered
separate from internal power header.

2.   Provisions to power everything off of PoE even if it is just a header
(or pinholes for user mounted header) to send the current to a daughterboard
voltage regulator that would then supply power back to the internal power
header. 

3.   Jumper to disable headphone and Mic-in jacks and enable onboard headers
for headphone and Mic-in to route to front case panel or elsewhere
