Hi Fernando,

and thanks again :-). A screen shot from my Device Mgr:

OK,

I understand...sad, because the original MS drivers give the same error: Code 10, and this means I don't even have USB 2 functionality for the USB ports.
Any idea what I can do as a work around?

Thanks!

No they didn't work directly after the Win 10 installation. And this was the reason I started to look for workarounds, your modded
driver seemed like the most promising alternative. I did try the original Dell driver for Win 7 64 bits, initially, and that driver worked.
But it fails to install under Windows 10. Regarding our question about the other devices, I could only find the PCI bus - no PCI Express
Root Complex. I tried other drivers for the PCI bus, and could for instance select your driver for the "PCI Express Root Complex" - it
installed, but still the USB 3.0 xHCI can't start (Code 10).

Hello again Fernando,

to answer your updated question: I didn't install the drivers for the Intel 7 series/C217 chipset (Device 1E2D and 1E26), this was done by the
Windows installation or by Windows Update. Do you have thoughts on this, maybe a work around?

Hello Fernando,

thanks for your support! I did as you suggested but the Intel(R) 7-series/C216 devices came back after reboot. I wanted to check if the situation was something
of my own doing, so I took the step to reinstall Win10 ver 1703 again from scratch. The Intel 7-series/C216 chips came directly after the Windows 10 installation.
Also, the Code 10 failing device USB xHCI Compliant Host Controller.

Since the Dell/Intel drivers worked for Windows 7 on this hardware - you haven't by any change made any mod for using the Windows 7 driver on Windows 10?
That would be awesome...honestly, I don't care if the ports have USB 3,0 speed or if they become regular USB 2.0, I just need the USB ports.

Still hope for some help :-)!

Thanks!

Hello Fernando,

many thanks for doing this adaptation!!! I just tried the new files, and unfortunately I still get the same error (Code 10) for the USB xHCI controller...
I start to suspect that I have something else that is causing the issue - maybe even a hardware problem.
I will probably try to reinstall Win7 64b later in this week to see if I can conclude something.

For now - many thanks for your kind support!!!

Fernando - thanks for looking into this, here is an updated dxdiag with WHQL verification off, and the latest drivers installed and in their non-functioning state.

I installed the drivers as you detailed a few posts back, and got the same reproducible results - older .42 drivers work, and .43 get a signature error.

I'm having a problem with the intel signed drivers on Win10 Creators update, even if I import the file says that the drivers are not signed.

I've checked the *cat files I have noticed one difference is that they don't display the day like in your screenshot. I downloaded the files from the OneDrive link.
