As you may or may not know, Gigabyte has a setting in the BIOS called xHCI mode.
It can be set to Smart Auto, Auto, Enabled and Disabled.
Disabled turns off USB 3.0 entirely and makes all the ports USB 2.0.
The other three operate slightly differently, especially with regards
to OS X and as you can see from my screen shots, it appears that the
Auto mode is the one to pick for OS X. It's the only mode that allows the OS to see the VIA USB 3.0 hubs for example an it appears to show more information about USB 3.0 devices.
I'm not sure the performance is quite there, as there's no performance benefit using either mode, but in Smart Auto the devices don't even seem to show up.
Note: This only applies to the Z77, H77, B75 and Q77 boards with integrated Intel USB 3.0 ports. Also note that xHCI and EHCI Hand-off has to be enabled or the USB ports won't work at all.
Edit: Also note the 'HS Port Switchable' settings. On the Z77X-UD5H there are four of these and they enable you to manually set your USB 3.0 ports to USB 2.0 mode if you chose disable rather than enable. This is handy for example during installation if you don't have additinal USB 2.0 ports on your case or via a bracket.

You request seems like a thinly veiled rant against Gigabyte.

Also your basic premise seems to be flawed (that because the hardware can support Windows 10, that if Gigabyte doesn't make work, Gigabyte is cheating you, no matter how old the motherboard is.)

Microsoft can state that XXX is the minimum requirements to run Windows 10.

But it is the minimum, not a guarantee that Windows 10 will work on that machine, or if it will run into problems or not. In a nutshell the hardware is only part of the picture, and the BIOS, and drivers and such are the rest.

If I have a 15 year old motherboard it might have all the specs needed to run Windows 10. But something that old you are not going to get new drivers. It just not economical for any manufacture to update drivers for something that old. Now it is very possible that the old drivers might work just fine in Windows 10. Good you are lucky (and in fact most will be lucky).

So we come to 'force obsolescence', to you that seems to mean that if it is possible, Gigabyte should make it work for you. Well from a manufacture's point of view you paid for product/service for a certain period of time that they have calculated into price you paid for your motherboard vs how much it costs to make and support such. I have actually no idea of how many years that Gigabyte will update drivers for their motherboard, but I do know it is not infinite. And most likely if they are going to test and fix drivers, they will start with their newest motherboards and as time goes on work backwards test/fixing older ones.

I notice that you request the spec's from other people's machines, but didn't do the same for yours.

And in the way you stated the question you neither want people to try to help you with your problem, or to use the information to buy a configuration that works.

For what its worth the machine I'm typing does have a Gigabyte motherboard in it, that frankly I really like. In fact I like it better than a similar Asus motherboard I have in another machines. Both machines upgraded with no real problems. I think there was a license problem on one of the AMD tools I don't use, and later I even found an update for it. I did do clean installs of both of them, but that was mostly because of the fact on one of them I had the classic upgrade problem. As in there a ton of settings that have to be transferred perfectly from one operating system to another, and doing so is extremely hard to do without any problems. Microsoft has got a lot better at it, but still problems can creep in, and they did on one machine. And I decided a clean install was the better approach then try to weed out these settings/install kind of problems one at a time.

I have also run both 32-bit and 64-bit Windows 10 on this machine.
