Did anyone have a good reason for not including support for a 
usb-1.0/2.0/3.0 interface seeing as we can write the driver ourselves 
and adhere to the standard?

Most chipsets these days have support for both port types. It would be 
very useful if the schematic provided tracks for both ootb.

BTW, I will be able to contribute development funds towards this project 
if required once we have a BoM.
