Analyzing the Installation of UMDF and KMDF 1.5 drivershttp://blogs.msdn.com/iliast/archive/2007/11/28/analyzing-the-installation-of-umdf-and-kmdf-1-5-drivers.aspxThe goal of this post is to provide an insight about the installation of UMDF and KMDF 1.5 drivers and to show how to overcome any potential problems. For demo purposes I'll be using the UMDF and KMDF echo driver, which can be found at the WDK (%WinDDK%\6000\src\umdf\echoenCommunityServer 2.1 SP1 (Build: 61025.2)re: Analyzing the Installation of UMDF and KMDF 1.5 drivershttp://blogs.msdn.com/iliast/archive/2007/11/28/analyzing-the-installation-of-umdf-and-kmdf-1-5-drivers.aspx#8679898Wed, 02 Jul 2008 07:06:07 GMT91d46819-8472-40ad-a661-2c78acb4018c:8679898Nster<p>What do you do if the driver is successfully installed, As claimed by devcon.exe BUT there's an exclaimation mark in your device manager? Inside setupapi.log it shows this error: </p> <p>Device not started: Device has problem: 0x25: CM_PROB_FAILED_DRIVER_ENTRY</p> <p>I checked all registry values associated with the driver install and they all seem to tally. BUT in the services registry where my kmdf driver service is installed, it shows this particular value in the Enum Key: INITSTARTFAILED (1). </p> <p>What can I do to rectify this issue? I have been at it for days now... </p> re: Analyzing the Installation of UMDF and KMDF 1.5 drivershttp://blogs.msdn.com/iliast/archive/2007/11/28/analyzing-the-installation-of-umdf-and-kmdf-1-5-drivers.aspx#8679900Wed, 02 Jul 2008 07:06:20 GMT91d46819-8472-40ad-a661-2c78acb4018c:8679900Nster<p>What do you do if the driver is successfully installed, As claimed by devcon.exe BUT there's an exclaimation mark in your device manager?

The installation was succesful, the PNP manager tried to load your driver, however your DriverEntry failed.</p>
