Hello Guys,

My product can not send data to my computer since I upgraded it from Windows 8 to Windows 10.

So I have one question, meanwhile a new version of the driver is released, how can I fix this issue ? 

Thank you per advance for your support.

    And this is why it's important not to rush into upgrades where the vendors of your critical components aren't chasing Microsoft's latest tangent.

    Aren't the WHQL tests supposed to prevent these types of issues? What has Microsoft changed that has broken the ecosystem?

    Hello Syrine,

    Thank you for your quick feedback.

    In fact, I have one customer among forty who is not facing the issue. Can someone let me know which files are installed and where they are installed by the VCP install tool ? 

    I want to check if it is not due to a change of the address of the folder.

    Thank you for your feedback.

    Hi ZBH,

    Hi Syrine,

    I have checked with a customer on his 2 computers, one powered by Windows 10 Pro, the second by Windows 10 Home.

    My product with my software made with the STM32 VCP driver is only working with the Home version.

    I can not understand the difference of the install of the driver on both operating systems and why this difference.

    Does anyone have a clue for helping me to solve this issue ? 

    B.R.

    Perhaps there are differences how different W10 version get their drivers. Like download from MS update or not. Have you looked at some Window 10 forums, there are several of them.

    Hi Mich,

    Yes I did : 

    http://blogs.msdn.com/b/usbcoreblog/archive/2015/07/29/what-is-new-with-serial-in-windows-10.aspx

    https://msdn.microsoft.com/en-us/library/windows/hardware/dn707976(v=vs.85).aspx

    ''In Windows 10, a new INF, Usbser.inf, has been added to %Systemroot%\Inf that loads Usbser.sys as the function device object (FDO) in the device stack. If your device belongs to the Communications and CDC Control device class, Usbser.sys is loaded automatically. The driver is loaded based on a compatible ID match similar to 

    https://msdn.microsoft.com/en-us/library/windows/hardware/ff538820%28v=vs.85%29.aspx

    .''

    I am not a specialist but I think the driver got to be updated. Am I wrong ? 

    In the README file released with the driver I can read ''Supported OS : Windows XP to 8.X''. There is not ''Windows 10'' on it.

    Thank you for your support. The issue starts to be very critical for me.

    B.R.

    I have Windows 10 and cannot get the MKI109V3 to work. The computer will not communicate with the board. The COM port will not open. The UNICO-included drivers are not compatible with Windows 10. I have dutifully followed all instructions included with the devices, however, as mentioned previously, the drivers do not seem to be compatible with Windows 10.

    I am not computer literate, I'm simply trying to help my son do a high school science project on bike helmet safety, and this is the only system MKI109V3 with MKI153V1 that will measure the G-forces he needs.

    I'm open to any and all suggestions.

    You might want to start a new thread in the sensor forum, it's going to get little traction in a 3 year old thread

    Hello ZBH,

    I'm facing the same problem on my Windows 10 right now. The post is couple of months old and am assuming you found a solution. Do you mind sharing with me please?

    The driver files will be installed at 

    C:\Program Files (x86)\STMicroelectronics\Software\Virtual comport driver\Win8

    Open a command prompt and cd into into this directory

    run

    dpintst_amd64 /LM

    Click yes on the driver installation boxes

    Hi Pavel—
    Thank you very much for your response. It truly confirmed to me that Windows had the appropriate USB drivers.
    Even though I had previously replaced the USB cord with another, newer one AND even though the board was receiving power, after your response I decided to replace the USB cord for the third time.
    Once I did that, the computer recognized the device and the UNICO GUI worked perfectly.
    Again, thank you very much for kind response
