Assigning USB 3.0 keyboard to a CPU Core

Hi there. I'm trying to save cycles on a thread by assigning my USB 3.0 slot (keyboard) to a specific core. I'm running an old X58 system 6 core, and would like to dedicate a core to actually each of my USB 3.0 mouse and keyboard devices. How do I do this?

Thanks

You don't. Just like you don't assign your GPU to a CPU core. It doesn't work that way.

that's ... not ... no?

sounds like you're trying to make a USB device function as a PS/2 device. if that's the case, there's no benefit to doing that.

It's not possible to assign the xHCI Host controller to a different core?

any modern OS can handle CPU affinity fine on its own. even if you could, it would have 0 benefit.

I'm 99% sure that's not gonna happen on Windows.

What cycle(s) are you trying to save?
