IMO any slowness of a Keyboard, hang etc, is not an issue of speed of transmission of the data but some other issue in the system.
A PS/2 KB will normally operate on data faster than human comprehension.

Is USB keyboard faster than PS/2?
I recently joined a CNC manufacturing company and they have given me a project to work on. So the issue is the MDI keypad used in their CNC machine is of PS/2 interface and they it slower and sometimes the system hangs because of this. Hence they want to change the keyboard interface to USB.
After doing a bit of research it appears to be that PS/2 keyboards are actually faster than USB keyboard (Or atleast there shouldn't be any noticeable difference between the two). And also that USB interface quite complex and costlier too.
So my question is which keypad interface does usual CNC machines have and does USB interface make a difference in data rate compared to PS/2?

what kind / brand machine?
I've never seen a machine control have any issues because of the keyboard speed.
