[CentOS] Hey Kudzu, leave that device alone!

How do I get kudzu to still look for new equipment but stop checking to 
see if some devices are present or not?

For example.  I have an ATEN USB keyboard/mouse adapter.  Sometimes at 
boot, it is not ready?  or something and then kudzu asks if I want that 
in or not.  Of course I want it in!!!  I may have to unplug and plug it 
back in, but don't bother me.

I have a similar challenge with the USB ethernet dongle....
