Thank you so much for your effort!! Me and many of those, who have been disadvantaged are grateful for your support :-)!
Sadly, the Intel-Driver for windows 10 x64 doesn't work with me. I got the ASUS Strix Z270F Gaming Motherboard with an Intel Z270 Chipset.
Generic USB xHCI Host Controller is the installed driver at the moment with following Error Code:
This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

(Somehow, i once restarted my computer and it worked until i had do make another restart... "Intel(R) USB 3.0 eXtensible Host Controller Driver" was the name in the device manager when it worked)

Hardware_IDs would be following ones:
PCI\VEN_8086&DEV_A2AF&SUBSYS_872F1043&REV_00
PCI\VEN_8086&DEV_A2AF&SUBSYS_872F1043
PCI\VEN_8086&DEV_A2AF&CC_0C0330
PCI\VEN_8086&DEV_A2AF&CC_0C03

With your Intel-Driver, i get following error code:
This device cannot start. (Code 10)

{Device Timeout}
The specified I/O operation on %hs was not completed before the time-out period expired.

Would be happy if you could help me out :-)

Hi Fernando

I used this one first:
>64bit Intel USB 3.0/3.1 Drivers v5.0.1.38 mod+signed by Fernando<

and after i tried out the DPInst, both with the same error message :-(

Im having a problem installing the asmedia drivers.
They simply dont show any sign of life on my Asus sabertooth z77 the intel driver worked flawlessly tho.

Device:
VEN_1B21&DEV_1042

Edit the last working driver seems to be asmedia_1.16.41.3.
I updated my firmware to the latest available version for 1042: 130125

the second one is not visible for me - there's no unknown device :-/

send driver file to my emaill please

yes exactly.. there's no Intel USB 3.0 Hub Device listet. however, under hidden devices, i found a xhci usb root hub - but can't do anything with it.
it was the same as now - there was the xhci compliant host controller and under system devices PCI Express Root Complex - now there's the pci bus and the intel usb 3.0 extensible host controller.
btw: the situation does not change, even when i turn on or off the xhci hand off support within the bios.

sadly, i cannot check it out anymore, since i thought, i'd clean up a bit and uninstalled all hidden devices under universal serial bus controllers.. :-/
it's quiet frustrating - since it worked once, and i don't even know how.. just after a restart without doing something specifically..

what also seems quite strange, is, that these usb 3.0 ports also don't work before windows loads. so they don't recognize any device i plug in (can't see them in bios), even though i can see, that my devices get power through those usb 3.0 ports. it's like the ports are broken but somehow not broken.. i don't know^^ will buy an usb 3.0 hub for that one usb 3.1 port which is from asmedia and is working :-)
