6.3 Developing Your Driver on Windows CE Platforms

In order to register your USB device to work with WinDriver, you can perform one of two of the following:

• Call WDU_Init() [B.4.1] before the device is plugged into the CE system.

  OR

• You can add the following entry to the registry (can be added to your platform.reg file):
  

        [HKEY_LOCAL_MACHINE\DRIVERS\USB\LoadClients\<ID>\Default\Default\WDR]:
        "DLL"="windrvr6.dll"
  

  
  <ID> consists of your vendor ID and product ID, separated by an underscore character: <MY VENDOR ID>_<MY PRODUCT ID>.

  Insert your device specific information to this key. The key registers your device with Windows CE Plug-and-Play (USB driver) and enables identification of the device during boot. You can refer to the registry after calling WDU_Init() and then this key will exist. From that moment the device will be recognized by CE. If your device has a persistent registry, this addition will remain until you remove it.

  For more information, refer to the Microsoft Development Network (MSDN) Library, under the USB Driver Registry Settings section.
