You know critical sections be crazy inverted. (When we turn it off, priority not a thing.)
USB IRQ only runs on core 0. (You know this because you have to look it up in source.)
I would interrupt into a context save of systick, then do calculation to figure out time. (Increase priority of ISR to bypass certain things.)
