I seached within Intel Support and what I got were Intel USB 3.0 Extensible Host Controller drivers for MICROSOFT WINDOWS 7.

Microsoft Windows 8 was released yesterday, October 26 and where is the compatible driver for it?
Could an Intel technical support representative feedback to technical support about this problem?

We should complain to Microsoft here:

Many people explained they had serious problems, in my case I simply tested the motherboard native (Intel ko) and secondary (Via ok) usb3 solution: I guess why similar drivers have different behaviours.
We're not talking about who's guilty, this is not my concern. We need a solution for this major problem, if I can't use a native usb3 driver 'cause it's faulty, than I ask to the main producer, which gives a direct functioning solution for Win7.
In this specific case, we're on an Intel forum, we have problems related to an Intel hardware, but the drivers are related to Microsoft because under Win8 it's the main provider.
So, you're asking a simple question, who's the producer.
Well, I'd like to answer that Intel may help, it's the chipset producer and gave us the functioning Win7 driver.
This is not a battle between us, we just need a solution.

I also have a similar problem but in my case it's with an external USB 3.0 4-port hub and not on the motherboard.
What's the brand of your 4-port hub? Some manufacturers of generic brands don't really include the real USB 3.0 chipsets in their product offerings.
It's a generic USB 3.0 4 port hub but I can guarantee it worked at highspeed under Win7. It even says highspeed "nonfunctional" in the Win8 Device Mgr.
Is this what's going on with Windows 8 causing this problem?
"..... the https://en.wikipedia.org/wiki/USB_Attached_SCSI USB Attached SCSI Protocol (UASP), a supercharged way to move files that's going to be natively supported by Windows 8....."

You have to be careful, my friend, when buying stuff that is generic. I have two external USB 3.0 HDDs that are generic brands. They all perform poorly. It was much later that I found out from one of my trustworthy Chinese manufacturers that native USB 3.0 chipsets are not included as doing so will drive up costs.
Let me say that even Microsoft doesn't provide a digitally signed driver, whatever.
The solution ekko suggested drastically improves performances, I tried with modified .inf files on a second pc, and the situation now is correct.
This is a hint for everyone: to test a usb3 properly we need a fast chain, ssd with os installed, usb3 port (and decent drivers), usb3 pendrive or external ssd.
'Till you stay on mechanical disks there's no way to reach the limit, 'cause we moved from 480 Mb/s to 4.8 Gb/s bandwidth, but you can always see the difference; and as Bowie wrote, a good external case is mandatory.
This is my second test on a Vaio with Ivy Bridge ecosystem (HM76 vs Z77).

Your statement supports what I have been saying all along: that the device driver provided by Microsoft in the installation media of Windows 8 is lousy. Intel owes to its customers a proper device driver compatible with Windows 8.
Bowie, I prefer not to quote all your sentence, but you're utterly right.
I don't blame Intel, but they have to resolve the problem giving Microsoft a help, a trick is not a correct procedure ever.
Talking about performances, I really ignore the causes of such a difference, maybe the burst speeds are determined by the chipset itself, but in different ways between the desktop and the mobile version.
The technical sheets referred to usb3 take a long time to read , with stable drivers we could proceed with other comparisons.
Oh, I did a speed test with the same machine via different controllers (1-VIA and 2-Intel, no differences between them, near 245 MB/s) on my Z77 pc; if you don't force the installation of Intel drivers, you're always limited to the maximum performance of usb2.
I noticed the same behavior on desktop and notebook, and that's perfectly normal, usb3 knows different ways to work: Intel did a lot of job simplifying an old structure, from Open to eXtensible Host Controller Interface, from BOT to UASP (where is it? ) but usb3 still resides upon legacy hardware/software and it's starting to spread only after Win8.
In this specific case, we're on an Intel forum, we have problems related to an Intel hardware, but the drivers are related to Microsoft because under Win8 it's the main provider.
So, you're asking a simple question, who's the producer.
According to your line of argument, Intel shouldn't be providing the Panther Point H77, HM77, Z77 drivers at all. And Renesas shouldn't either.
Since this discussion forum software is so NIGHTMARISH to deal with when using special characters, I uploaded the files and instructions here:

Hope this helps!
