Yup, I havnt tested but I bet that's it.
Actually the hub is pretty cool, I can turn off each device with a button when not in use, mostly for latency superstition (throughput adds up fine) but I like it.
I do have enough USB ports, but don't like the thought of how much current 10 devices are drawing on my power supply...lol
With SLI, and OC the numbers are close to my power output.
Either way at least I know what's up. Thanks for the response.
