@Fernando,

Here are more details about the 'signature' problem I have:

1) with W10 x64 v1511 (french version) I observe this signature abnomalie (for Controller Host and Root Hub), however the Intel USB 3.0 modded driver is properly working.
Why this 'mismatch' about signature ?


2) with W10 x64 Preview Build 14366 (english version) I observe this:
Trying again to import CA, W10 detects 'Certificate "Win-RAID CA" already in store' (so I assume CA in well imported):


Native driver:


Intel USB 3.0 Modded driver installation "First step":



Have disk method:


Signature problem detected (Code Error 52):


So, I don't understand whe signature mismatch in case 1) and the Error Code 52 in case 2).

@Fernando,
Thanks, I understand your analysis, however the 2 "Intel(R) C610 series/X99 chipset USB Enhanced Host Controllers" are USB 2.0 only as reported here:
Controller 1:


Controller 2:


So, i don't think to a potential interference.

Moreover, with W10 v1511 I got no Intel USB 3.0 modded driver installation 'problem', except the 'signature' abnomalie which is seen as 'authentic' on one sub-menu and seen as 'without numerical signature' on one other sub-menu.

So, I let confused.

@Fernando,
Yes, i have installed "Intel Chipset Device Software v10.1.2.19 WHQL" after completed the Build 14366 installation because there were many 'flags' within the Device Manager Panel.
After installed it, all 'flags' disapeared !
May be I should have to install modded USB 3.0 drivers prior to install the Intel Chipset Device Software ?
I see in Relese note of Intel Chipset Device Software a fix has been done on USB 2.0 controllers for x99 systems.

I 'll do test to try to replace Intel USB 2.0 drivers with MS USB 2.0 drivers and let you know the results.

@Fernando
I have uninstalled the 2 specific USB 2.0 controller (uninstall option Device Manager) and tried to install modded USB 3.0 'first' step.
I have let the Intel Chipset Device Software WHQL installed because i don't see an easy 'uninstall' option.
Here are the screens:
You see 'signature' Err code 52 problem is always present.


After reinstalled the native MS USB 3.0 (automatic serach option) i come back to the native screen:

Hi Fernando, I am running a ASUS G75VX, I had Windows 10 on it but run into countless driver issues. I reinstalled Windows 8.1 with Update X64 Ver 6.3 Build 9600.

I wish to use the drivers you updated but when I try the force update I get a message that says The folder you spesified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems.

The USB 3.0 eXtensible Host Controller Hardware Ids are:

PCI\VEN_8086&DEV_1E31&CC_0C0330
PCI\VEN_8086&DEV_1E31&CC_0C03

and the USB Root Hub (xCHI) Hardware Ids are:

USB\ROOT_HUB30&VID8086&PID1E31&REV0004

One of USB Root Hub's shows:

USB\ROOT_HUB20&VID8086&PID1E2D
USB\ROOT_HUB20

So basically is there a way I can modify the inf information so that this USB 3.0 driver can install and work on this system?

Would you need more information in order to address this?

Thanks for help, much appreciated

Hi fernando.

First of all, thank you so much for these modded drivers.

I tried installing the latest v4.0.5.55. Like you said, I first imported and installed the certificates and then proceeded to install the drivers using the have disk option.
First I installed the controller driver, but in my system the name was already Intel(R) USB 3.0 eXtensible Host Controller, so there was no change in name. However, I noticed that the name of the hub changed to Intel(R) USB 3.0 Root Hub even before I installed the hub driver. Anyway, I proceeded to install the hub driver too, and rebooted. But sadly, I'm not getting USB 3.0 speeds when I copy content to my pen drive (SanDisk Ultra).
Please do take a look at this screenshot and see if there's anything wrong that I did. I have been struggling with slow USB speeds on Windows 10 as long as I can remember.

Hi fernando.

These are the list of system devices. Should I install switch driver for any of these?
