At least not meant to connect direct to I/O but maybe through a comparator, still gives it USB, just not at zero cost.
VUSB does 12mbps? they connect direct do they not?

V-USB is low-speed only. And, the comparator won't cut it for us. I still haven't found any way to read from the peripheral register that doesn't take 17 cycles!!! So, unless some other mechanism of ninjaing the data appears, appears full-speed is dead.
