Which driver is servicing them? if it an xhci driver... turning that off, 
either in bios (what I did) of via software may let the ohci driver work 
and split them up a bit. (I at least got two doing this) This basically 
makes your machine USB2 and not USB3. However, it may allow you to 
separate at least some of you USB parts. On this machine with xhci running 
every single plug ended up on the same USB bridge (all 10 of them!) but 
turning xhci off in bios split the plugs into two bridges (front and back 
in my case) and allowed me to give my USB audio a higher priorty while 
leaving my mouse and printer at lower priority. (the mouse has since been 
replaced with a ps/2 mouse) This may help:
