The DriverWizard has created a sample application which diagnoses your hardware.

  C:/WinDriver/wizard/my_projects/l123456_files.txt
         A detailed overview of all the generated files.

  C:/WinDriver/wizard/my_projects/l123456_diag.c
         The sample user-mode application which diagnoses your
         hardware using the usb_diag_lib library.

  C:/WinDriver/wizard/my_projects/cepb/l123456_diag.pbp
         Microsoft Windows CE.Net 4.X Platform Builder Project File.

  C:/WinDriver/wizard/my_projects/cepb/l123456_diag.pbpxml
         Microsoft Windows CE.Net 5.0 Platform Builder Project File.

  C:/WinDriver/wizard/my_projects/l123456.inf
         A formatted reference file for Windows that contains
         information about installation files and devices, such as
         filenames, version information and so on.

Compiling this project:
  For MS Platform Builder, open CEPB, insert cepb\l123456_diag.pbp (or
cepb\l123456_diag.pbpxml for CE 5.0) to your platform and build.

Converting to a GUI application:
  This sample was written as a console mode application (rather than
  a GUI application) that uses standard input and standard output.
  This was done in order to simplify the source code. You may change it
  into a GUI application by removing all calls to printf() and scanf()
  functions, and calling MessageBox() instead.
