Pool usb ports. Often is not often enough?

Hello.

The “manual” (or user guide; help.chm) says:

Selecting this option enables the check carried out for presence of USB connection, carried out every milli second.

not only every millisecond?

So It pools every milli second no matter if I check it or not, but why would I want it to pool the ports even more?

Thank you!

EDIT: oh, gawd you’re doing it on purpose aren’t you
