Are PS/2 ports still operating on hardware interrupts these days? I would expect these to be emulated as USB devices at this point, depending on whatever I/O chipset is in play.

The bit about USB asking the CPU is kinda true? My understanding is that it’s a packet protocol of sorts, so it’s really just writing post-it notes for each button press and leaves them on the CPU’s whiteboard for later.

Yes, it’s true the the USB protocol has to “wait” but it gets the message sent so much faster that it doesn’t matter. Still interesting stuff though!
