It’s not functionally useless, it supports a mouse, keyboard, printer or even an iPhone (non pro) perfectly fine at full speed. It also probably has enough speed for the average cheap terrible quality USB drive that the buyer of a $600 PC might have.

The assortment of cheap USB sticks I have do not surpass 400mbit/sec. Not even the ones labeled USB3.0 or High Speed.
