temporary enable back USB port

From the link, looks like it can only be done from the EPO server which I don't have access to?

Is there a way I could disable my USB ports without using McAfee DLP method?

There is a video to set exclusions but don't see a video on
"How to block all USB drives using Host Data Loss Prevention (Host DLP) 9.x, leaving other USB types
of hardware (keyboard, mouse, and so on) unaffected"

then best contact McAfee - they should be able to help

Just one last question, does anyone know what are the files I can backup first prior
to applying the McAfee DLP (as well as after) so that I could restore back that file(s)
after disabling the USB (& I could restore to the state after applying to disable USB)?

Or my idea is too simplistic?  If this way of taking backup could have worked, then
we're bypassing the security enforcement?  

Perhaps backing up the registry?  

Nobus, is there a user community for this McAfee product which I may enquire with
(to identify which files are changed/updated when McAfee DLP disables USB) as I'm
not the appointed McAfee appointed contact person in our corporate?
