Enumerate Hubs (Root Hubs and External Hubs). Given the name of a hub, use CreateFile() to open the hub. Send the hub an IOCTL\_USB\_GET\_NODE\_INFORMATION request to get info about the hub, such as the number of downstream ports. Create a node in the tree view to represent each hub. 1. Enumerate Downstream Ports. Given a handle to an open hub and the number of downstream ports on the hub, send the hub an IOCTL\_USB\_GET\_NODE\_CONNECTION\_INFORMATION request for each downstream port of the hub to get info about the device (if any) attached to each port. If there is a device attached to a port, send the hub an IOCTL\_USB\_GET\_NODE\_CONNECTION\_NAME request to get the symbolic link name of the hub attached to the downstream port. If there is a hub attached to the downstream port, recurse to step (2). Create a node in the tree view to represent each hub port and attached device. USB configuration and string descriptors are retrieved from attached devices in GetConfigDescriptor() and GetStringDescriptor() by sending an IOCTL\_USB\_GET\_DESCRIPTOR\_FROM\_NODE\_CONNECTION() to the hub to which the device is attached. -The file Display.c contains routines that display information about selected devices in the application edit control. Information about the device was collected during the enumeration of the device tree. This information includes USB device, configuration, and string descriptors and connection and configuration information that is maintained by the USB stack. The routines in this file simply parse and print the data structures for the device that were collected when it was enumerated. The file Dispaud.c parses and prints data structures that are specific to USB audio class devices. +The file Display.c contains routines that display information about selected devices in the application edit control.
