[CentOS] Restarting mouse services

I move my notebook around my office.  Sometimes I am using the internal 
pointers, sometimes a USB mouse, and sometimes a USB keyboard/mouse 
adapter that is plugged into a kvm (actually two of them).

With one of these USB k/m adapters, when I plug in, the system fails to 
recognize the mouse (but no problem with the keyboard).  The 2 adapters 
are the same brand/model (Aten), but the KVMs are different Aten 
masterviews.

Of course I would like to figure out why this is happening and get it to 
stop,

but meanwhile is there a way to restart the mouse services.
