A Simple Question...

Hi again!
I?m trying to understand how Windows make a 1-to-1 relationship between PID and VID of my device and the internal name of the driver used by Windows Driver Kit RTM examples. Specifically, I?m studing the “usbsamp” code (WINDDK\6000\src\kmdf\usbsamp). So, I would like to know the follow:

  1. Is the connection between PID/VID and internal driver name set in .inf file?
  2. Where I set the internal driver name?

Thanks!

Take a look at usbsamp.inx you will see the PID/VID described as follows:

[Microsoft.NT$ARCH$]
%USB\VID_0547&PID_1002.DeviceDesc%=usbsamp.Dev, USB\VID_0547&PID_1002 ;
OSR USB-FX

Now notice there is a name after the equals sign of usbsamp.Dev, this is
then used to select the additional sections:

[usbsamp.Dev.NT]
CopyFiles=usbsamp.Files.Ext

[usbsamp.Dev.NT.Services]
Addservice = usbsamp, 0x00000002, usbsamp.AddService

[usbsamp.AddService]
DisplayName = %usbsamp.SvcDesc%
…

Where the CopyFiles indicates the files to copy, the Addservice indicatated
the service name in the registry to add, and the DisplayName indicated the
name the device manager will show.
