How to install UMDF-based class filter driver?
in [Device Drivers]
|
From: Leafbanana on 1 Jun 2010 02:27 Hi, I used to have a WDM-based class filter driver and a setup application which calls the "SETUPAPI.DLL InstallHinfSection" with the INF DDInstall section passed into the function. Now I am trying to port the driver to UMDF-based version. I modified the INF as per WDK required, but I got an installation problem - the UMDF co-installer "WUDFUpdate_01009.dll" can't be triggered by using the setup application. However, installation via Device Manager with the INF is OK. How should I solve such problem? Appreciate your replies.

I don't know if this scenario has ever been tested d "Leafbanana" wrote in message news:5B27205B-19FF-4198-8DC7-92FD020E16F6(a)microsoft.com...

You need to intercept kernel streaming ioctls for that. In most cases, you don't want the overhead of UMDF involved. -- Tim Roberts, timr(a)probo.com Providenza & Boekelheide, Inc.

Hi Tim, You are right, the driver is for intercepting kernel streaming ioctls. Could you please explain more? Why I don't want UMDF? Any problem with it? Thanks.
