Embedded chips (i.e. microcontrollers) won't support USB 3 for a long time (think 10 years at least). Very very few even support USB 2 High Speed and that was released 15 years ago.
There's a division forming in embedded where "real embedded" like my dishwasher uses an 8-bit microcontroller to turn pumps and valves on and off in sequence which may never have a USB and for price reasons will never support above USB1. It has very little stored state to talk about, and the more state and sensors the less reliable and productive it'll be, so that's unlikely to change any time soon.
The other division of embedded is best described as duct taping a tablet computer permanently to a refrigerator, and those will have USB-C like next year. In the '80s we put TVs and VCRs into the same case and called it innovation... This is the '10s version.
One type of embedded is like industrial control, the other type is like product tying.
One segment is extremely price conscious because China sells the USA 10 million value engineered dishwashers per year, and using a microcontroller that costs $1 more to do something the market is completely uninterested in is a $10M loss which the market will not tolerate. The other segment is luxury gadgets for rich people where price is no object and sales never exceed the thousands, although the web pages are extremely elaborate and expensively designed.
