I have a follow up questions from a Q&A I was reading-up, PS/2 vs. USB keyboards: performance and energy consumption.

  1. I have a USB-to-PS/2 adapter. I can attach it to a USB port on my computer and it gives me two PS/2 ports, for a keyboard & a mouse. If I use this adapter, would my processor be polling the devices or rather getting interrupts from the peripheral devices?

  2. I don't have a problem with using USB 3.0 or PS/2. I am under an impression that USB 3.0 is supposed to fix this polling behavior. Is it true? If it is, then does it mean that a USB 3.0 mouse and keyboard would be at-least as fast as PS/2, if not more?

  3. My motherboard has a green and purple combo port. So, if I get a PS/2 splitter instead a USB-to-PS/2 adapter, would it be faster?
