Can't Get Three USB Monitors to Work

I could unplug all my USB devices from my computer and plug them into a powered hub (that would free up six USB ports on the back of my MB). The short dual USB cables that came with these monitors aren't long enough to reach my computer case (under my desk). I could do as you requested, but it's a hassle that I'd rather not go thru if I don't have to.

James,
I believe that I have eliminated the powered USB hub as a possible source of error. Have my log files revealed anything else that may be suspect? I thought I might need to change something in my BIOS. The only thing that I could see was disabling legacy USB 1.1 ports. When I did that, none of my USB monitors would work. I did make one update to my computer this weekend, I upgraded my CPU from a FX-8150 to a FX-8350, no change with regard to functionality of the USB monitors. My motherboard is an ASUS Crosshair V Formula. I've asked ASUS technical support for help. They appear to be stumped. Anything else I should look into?
