Thanks for your comment.

If my Step 7, listed below, is not the action of including SDKSamplePrivDeveloper.pfx into my driver project, I need to figure out how to include this pfx in the VS2005/WM5SDKPPC IDE.

.....
7. In the VS2005/WM5SDKPPC IDE, select SDKSamplePrivDeveloper.pfx as the Project->Properties->Authenticaode Signing->->Certificate value of the VS2005/WM5SDKPPC driver.
.....

FYI, all the pfx-relevant project properties I have configured are:

.....
Debugging->Remote Executable - %CSIDL_PROGRAM_FILES%\cttunim\cttunim.dll
Deployment->Deployment Device - Windows Mobile 5.0 Pocket PC Device
Deployment->Remote Directory - \Windows
.....
Build Events - all three events are empty now
.....
Authenticode Signature - Yes
Certificate - SHA-1 Hash=1049B790EDA3C369E9C206B44AF16B2657CC1555
Provision Device - Privileged Certificate Store

Are there any other project properties I need to configure? Your further comment is extremely welcome.
