Really thx Fernando (Dieter) with Normal WIN10 Driver and Fresh Install ,i got Around 30mb/s on my USB3 Ports. With your modded now 95-115mb/s ....
And i search the Whole internet and found nothing. Then here 5 min and all go.

I Controller and Hub enough ? Or i also need install Switch for Anything ?

PS : Intel 8 have V5 and 7 V1 there is nothing newer ?

@Fernando:
I have 6x USB2 and 4x USB3... they work fine ,but i install the Switch anyway now.

Am stillwondering why the original win 10 drivers slows down the USB3 Ports and your mod driver makes it faster. In google there is no help actually.
such errors should always be assigned to the devices ( broken,defective USB Stick, External hard drive ) , I only read there.

glad i found this here.

Hi again it was working fine ... but now after some restarts i got the same old slow speed on USB3 i have nothing changed ?

Yes from Begin to end it was constant 25mb/s Write today .... With External USB3 Drive.... and test with 5GB video file.

After i Install all your Drivers again ( Now with DPInst64 ) and make Restart, i got the 100-110mb/s Write constantly back again. So the reason is not the connected device !

So i think your drivers got delete or overwrite anything by itself or win ?

I'll see how long it lasts now

You do know old utility UsbView, do you? Today I searched for it and discovered two things: (1) Internet offers very old version of utility for download, and (2) there are up to date source files for this utility at github.com
(https://github.com/Microsoft/Windows-driver-samples).

So I went for source files and managed to build fresh version of UsbView
http://www.mediafire.com/file/u1rsrjzq2wcls9l/usbview.zip

Bundle contains two executable files - x86 and x64.
Both files were built with Windows10 as a target platform. I tested it both on Windows 8.1 and Windows 10 and it worked.

There are command line parameters to save full report into either txt- or xml-file. Execute with "/?" to see the help on these parameters.

@mbk1969 Your version work on Win7_x64 Z97 mobo,too.

@Horus Cool!

[If i have posted this incorrectly, please forgive that I am new here]

I hope that my signature contains all the relevant information about my system: in brief, it is a Dell Laptop with two Intel 3.1 Gen 1 ports and one INtel 3.1 Gen 2 port of type C supporting DisplayPort and Thunderbolt.
I installed the DPInst drivers at the start of this forum hoping that it might by itself solve my problem, but it has not.

My problem is that as a result of some random behind-the-scenes upgrade, My display port monitor, connected by a USB-C to DIsplayPort cable, has ceased to work. And in the device manager of my machine, indeed I see that the UCSI USB Connection Manager has a yellow triangle, and reports the error that "the device has been stopped because it reported problems. (Error 43)". I could find no advice online except to uninstall the device and hope for the best.Unfortunately, I can uninstall the device, but that doesn't uninstall the driver.

Could you suggest a way to truly uninstall the software driver itself, or suggest some way to replace it with one that will not give me Error 43?

Of course, I don't actually care about Error 43 per se -- I would like to get video flowing to my display port monitor.

If I uninstall the device, and then physically erase the .sys file and its backup, will that cause Windows to reinstall a driver from Windows update?
The driver for this USCI USB connection manager is the single file UcmUcsi.sys

Thanks very much indeed,
Scott

Thank you for such a prompt reply. I'm embarrassed to say that I made two errors in my original post. One is an error of fact: The driver for the "USB Connection Manager" is UcmUcsi.sys; I've corrected my post. The other error is obviously just one of explanation: this USB Connection Manager seems to be it's own device family. It does not use the USB drivers directly, but rather its driver UcmUcsi.sys uses the USB drivers. I will attach a screen-snippet from my device manager which I hope will make things clearer.
(actually, I don't see anything but the "Quick Reply" button;nonetheless, after I post this text, i'll try to post a picture.
The yellow triangle I'm seeing is NOT with USB drivers, and I'm NOT suggesting uninstalling THEM. The yellow triangle is next to the USB Connection Manager. That device has a single file -- UcmUcsi.sys -- as its driver.
My question about uninstalling the driver was this: Because the problem seems to be with a "device that is reporting problems", one thing I wanted to do was to make certain that the driver files I have are intact and not corrupt. One standard way to do this is to uninstall the driver and then either reboot or choose to detect new hardware. WHen you do this, in principle, Windows goes and checks in a central database for the correct driver to installed. For this to work, two things are required: There must be no driver instralled already, and the Windows Update back-end has to know about the device. Normally, I thought, there is a checkbox in the Uninstall dialog which I can check to delete the driver softwrare form the local database. But in this case, with the USB Connection Manager, I did not see that checkbox. So I couldn't uninstall the driver in the usual manner. This is why I was asking if I could uninstall the device and then manually go to the driver-store and erase the file UcmUcsi.sys. I was asking if this will trigger WIndows to go to the Net to find the **Connection Manager** driver software (not the ordinary USB software). Or perhaps it is a very stupid thing to erase driver files in this manner
And the other question I was asking was if by some miracle you included a UcmUcsi.sys driver in your latest Intel USB package. As far as I could tell, you had USB controller drivers only. I would love a UcmUcsi driver package that I knew was not corrupt. I note that whatever it is, the Microsoft driver dates from 2006!! So I imagine that there is a new version from ??? (Intell?).
I found several posts online which desribed an identical problem to mine, and said that in the end the solution was a motherboard replacement. But there was one post which described the same problem and said that a clean install of windows fixed the problem. Imagine! replacing a motherboard because they can't be bothered to avoid corrupting a driver during an upgrade of Windows, combined with not bothering to make an install package for the specific driver so that it can be 'refreshed'
Bottom line: i did want to uninstall a driver by uninstalling the device and nuking the file, but i wanted to do this to trigger the automagic restoration of the file that would take place as a result. And I was hoping that you might have a package to install those USB-related drivers.
Just to complete the picture, the hardware ID of the USB connection Manager is ACPI\VEN_USB&DEV_C000

To answer your specific question:
>What happens when you do a right-click onto the Intel USB 3.0 Controller, choose the option "Uninstall device" and reboot thereafter?

THe answer is that I have no problems with your drivers for my USB -- on the contrary, they restored all sorts of nits that hand bothered me for some time. So I didn't uninstall that device. I right-clicked an uninstalled the device with a yellow triangle, not a healthy device. And what happened when I reboot after the uninstall is that after the reboot is over, I have exactlty what I had before: a yellow triangle and Error 43 for that device. (Of course, I haven't uninstalled AND erased the drivers yet).
I hope this is clearer. And I thank you very much for your help.

Do you have any modded USB 3.0 drivers for Intel series 6 C200, or even later than the year 2010 version from Intel?

I had already installed the latest drivers from Renesas 2.1.39.0 which you have listed on your site. The Generic USB drivers from Microsoft are dated year 2006. This seems to work ok in Win7 with the exception that it shows only high-speed rather than super-speed.

My issue is more with Win10 where the transfer speed slows drastically when transferring files, taking hours instead of minutes to copy files to a USB external hard drive. This is on a dual boot Win7/10 using the same USB port and hard drive.
