Thanks for chiming in! Lemme just plough through your statements...
> "No mobo will work with out an OS installed"
Haha, I don't see the logic in this phrase
As I said, the USB 2 hubs work even without a running operating system (you mean that with "OS", don't you?)
> "You need your mobo drivers installed, usually this is with the chipset driver."
Ok yes, but as a casual consumer there is no way to change the southbridge drivers which control the USB hubs, right?
> "With a custom build you need to install all the drivers for your mobo for it to operate correctly"
Yup, this is what I am at! But how can I install a driver on the mainboard?
> "Can you please list your complete system specs....be as detailed as possible."
Nah thanks, I am fine. As I said initially, my mainboard is the GA-790XTA-UD4. I think this is the only component which really matters for this issue.
> "To create a bootable USB, you 2 things, first the ISO and software to create the bootable device"
Cough, cough. I think I already said that I successfully created a bootable flash drive with Win 7.
> "the USB 3.0 header is not plug in to mobo or you don't have the correct driver installed"
The hubs work flawlessly under control of Windows 7.
So........... in a nutshell, my title says everything in fact.
