Pointer to a string containing the device ID.
To obtain the device ID, enumerate the available WIA devices on your machine.
|SUCCESS||The function was successful.|

This feature is available in LEADTOOLS version 16 or higher.
Use [LWia:SelectDevice when working with multiple WIA devices installed on a machine in order to select the WIA device without displaying the Select Device dialog. To do this, enumerate the WIA devices by calling the LWia::EnumDevices function. Then use it to keep a list of all received device IDs. Then call the [LWia:SelectDevice function using the device ID of the device to be selected.
WIA 2.0 does not support cameras or streaming video.
When using the high-level LWia::AcquireSimple, it is not necessary to call LWia::InitSession, [LWia:SelectDevice, or LWia::EndSession because it handles session initialization, device selection, and session end automatically.
