I understand the concern of sunbe.
I explain my experience when i have updated Intel USB 3.0 ports driven by the MS driver (in the box W10 1511) to the Intel modded v4.0.2.42

The 1st pitfall is if you want update any Intel USB 3.0 ports driver you should be aware that all the other Intel USB 2.0 ports are also managed with the same driver.
So, in my case i have had to unplug provisoirly the USB 2.0 keyboard/mouse from Intel ports to plug them on any available USB 3.0 ASMEDIA ports, so i did not lost these peripherals during the process update.

The certificate update option b) worked fine. (however some typos in the b) text does inverse 'next' and 'ok' clicking).

The controller update is not a problem, i have used the 'have disk' because the native driver date was more recent than the modded driver date.
Yes, reboot is mandatory after controller update.

The 'yellow' unknow device has to be updated with an appropriate driver.
The difficulty comes, in my case, with HUB driver selection. The choice was not really obvious between a large number of choice.
Finally i have selected the manufacturer 'Intel' not 'Intel Corporation' and then founded an appropriate entry such as:


and finally got after a reboot the modded driver up and running well:



However, i see a new item MTT was intalled automatically.

Fernando, can you explain this:

After controller update:



So I update the unknown device to Intel USB 3.0 Root Hub and things go awol, pics coming

sunbe,
yes, you have to update the driver of this 'unknown device' with the 'Intel USB 3.0 Root Hub' modded driver and this should work.

Seems to crash regardless of if i install Intel usb 3.0 root hub, usb 3.0 hub, or usb 2.0 hub to the unknown device. I guess the driver really isnt compatible with mine.

Sometimes I also get device enumeration failed in Device Manager.
Any ideas?

@Fernando,

Please, can you have a look on my last picture of my previous post about the strange Intel "MTT" USB2.0 item (Concentrateur MTT USB 2.0, modded driver v4.0.2.42 WIN-RAID CA) created automatically when I have updated to Intel USB3.0 modded ?

A performance compare between ASM USB 3.1 driver and Intel USB 3.0 driver using the same USB 3.0 key gives ASM driver 21% more performant than Intel driver.
The both drivers do support TRIM (done before each ANVIL benchmark):

INTEL modded driver:



ASMEDIA standard driver:

Any idea what could be going wrong with mine?

Does the native Microsoft USB 3.0 driver works fine for all your Intel USB 3.0 ports and US 2.0 ports ?

I swear my pc crashes after i install the Intel usb 3.0 root hub or usb 3.0 hub driver to the unknown device.

@Fernando
After the update, as you can see in my post 286# a strange "USB 2.0 MTT Hub" item automatically has been installed.
It is like in your system.
What is this MTT stuff ?
Very strange again when we update Hub USB 3.0 this update also Hub USB 2.0 as already I reported you.

Fernando, it would be really really great to have a performance comparison between the Microsoft drivers and the modded Intel ones.
