Confused, I believe the problem is that even with the USB hub's 5v supply cutoff, it will still draw power from the USB cable plugged into the USB port on the motherboard. That's why in the thread I mentioned above, Ricky and gospeedracer were describing a setup where a relay driven by +5V from a PSU molex would be used to switch the +5V power line going into the USB port. So, I guess my question is: will I have this problem if I use an ITPS as my SDC? That is, does the ITPS completely shut off power to the PSU, or is the PSU still able to provide power to the USB ports?
