WIA Root Item

A WIA root item is a folder item that represents the device itself. A WIA root item is marked with WiaItemTypeRoot and WiaItemTypeDevice and contains device attributes such as:

• The manufacturer name

• The device name

• Driver attributes (including the driver version and the user interface CLSID)

Imaging applications obtain the root item in the WIA item tree by calling the IWiaDevMgr::CreateDevice method (described in the Microsoft Windows SDK documentation). The application then uses the root item to enumerate the tree, thereby gaining access to individual child items.
