Couldn't quite remember how it worked, just that USB didn't CPU interrupt:-)

Modern CPUs can manage what interrupts them. Almost nothing actually does.

Computers have a CPU just to get in the way of things interrupting the main CPU.

I'm remembering from back in the ol' single core days too. Where an interrupt was, well, an interrupt.

If you want a USB host controller to interrupt your CPU, I can recommend some nice embedded SoCs
