UHCI sends a more regular stream of interrupts, since it needs the
software to tend things rather often. OHCI and EHCI tend to use

No. Keyboard and mouse already add entropy. If you take anything else there's
a theoretical risk of someo

I think most controllers interrupt every frame.
That would be a very poor source of entropy.

After looking at Robert Love's patches for net devices contributing to the
entropy pool, it occurred to me that perhaps USB controllers should also
contribute (possibly on a config variable).
AFAICT, all we need to do is add SA_SAMPLE_RANDOM to the request_irq call
flags in the host controllers.
