  • devcon error for WinPe 3.0

    Using the Windows 7 AIK I created a bootable UFD with WinPE 3.0/BurnInTest very easily. There are some differences compared to previous AIK versions, and it seems the devcon.exe does not work properly. It says on the Microsoft download page as well that devcon.exe is made for 2k, xp and 2k3. Does anyone know of a tool that works in Win7/WinPE 3.0 to install drivers for com and lpt ports?

    This is the error I get:
    X:\windows\system32>net start serenum
    The requested service has already been started.
    More help is available by typing NET HELPMSG 2182.
    X:\windows\system32>devcon install x:\Windows\inf\msports.inf ACPI\PNP0501
    Device node created. Install is complete when drivers are updated...
    Updating drivers for ACPI\PNP0501 from x:\Windows\inf\msports.inf.
    devcon failed.
    X:\windows\system32>net start parport
    The Parallel port driver service was started successfully.
    X:\windows\system32>devcon install x:\Windows\inf\msports.inf ACPI\PNP0401
    Device node created. Install is complete when drivers are updated...
    Updating drivers for ACPI\PNP0401 from x:\Windows\inf\msports.inf.
    devcon failed.

    Did you test it and find that the serial port test and parallel port tests did not work?

    If so, from a search of the Internet, it seems that you may need a newer version of devcon. E.g.

    If this does not work, please let me know.

      You can also use DISM to inject the drivers into your WinPE. Example:

      Dism /image:C:\test\offline /Add-Driver /driver:C:\test\drivers\driver.inf

      If you just want to add drivers after WinPE loads, you can use the built-in DRVLOAD app:

        Thanks. I will test BurnInTest WINPE3.0 when I get some time and update our documentation.

          We have just modified BurnInTest 7.0 (currently in Beta) such that when run from WinPE it will now configure the COM ports before running the serial port test. Hence the previous configuration using devcon is no longer required, and the problem in this post is not relevant for BurnInTest 7.0.

          The current Beta of BurnInTest 7.0 and the updated draft WinPE 3.0 document can be found here:
