This is just an off the wall guess.  Wouldn't such entropy already be
collected at a lower level, like raw usb traffic?

Hi,

While analyzing the entropy sources for the random number generator in
drivers/char/random.c, I saw that a USB mouse and a USB keyboard does
trigger the add_input_randomness function to be triggered.
I need to reread what I write :-)

I mean that the USB mouse and USB keyboard does *not* trigger the
add_input_randomness function.

Is that intended?
