And should the desired "USB" be USB2 OR USB3?  USB3 is supposed to be 
backwards compatible.  However, USB port specs are apparently not frozen 
in design.

Also note that the USB3 specs seem to imply that USB3 should be able to 
supply 1.5A (sometimes 6). Thus the K3 would most likely be required to 
supply this additional power. More cost and complexity.  Plus the DC 
supply to the K3 would most likely have to be upgraded to provide this 
extra current.
