Will a USB to PS/2 adapter come with the benefits of a PS/2 to PS/2 connection?

Question

Will the benefits of ultra low latency "forces the cpu to deal with the ps/2 input" exist with a USB to PS/2 adapter or will the adapter be a limiting factor?

PS/2 is interrupt driven while USB depends on the host to poll attached devices....so you'll lose the latency benefit of PS/2 simply because the adapter uses USB.

A USB to PS/2 adapter (like the little green ones Logitech packs with some keyboards) is only compatible with specific keyboards!

These keyboards support both USB and PS/2 natively and switch modes when the adapter is connected.

Using this adapter is no different from using a PS/2 keyboard, because keyboards that work with the adapter are PS/2 keyboards.

At the time I used such an adapter (no PS/2 or Parallel ports) the adapter did not speed up anything to any measurable degree. Just the same is how I would put it.
