Decoded Port Status/Change for Hub Device
The following form displays the port status information returned by the Hub on a hub-class-
specific GET_STATUS (GetPortStatus) request, decoded according to USB Specification 1.0:
The form displays the number of the port for which status information was requested in its title.
Corresponding change information can be viewed using the Next button at the bottom of the
form. The scrollbar at the right side of the form permits viewing of all the entries. If the device
only sends a portion of the data, the Detective software marks missing entries with “N/A”.
4.8.2.3 Decoded Requests for Other Device Classes
The Detective software incorporates support for standard and Hub Class operations directly in
the application code. Other classes are added at system startup time, by reading a set of library
files (e.g., “CLS_HID.DLL” for the Human Interface Device Class); these additional classes will
automatically show up as options on the “Select Device Class...” dialog box. Contact CATC for
information on the availability of these additional Device Class files.
4.9 The Search Menu
The CATC Detective software provides several options for searching through the recorded USB
traffic, allowing the user to find specific packets based on packet number, marking, or content.
The three most common actions (Go to Packet, Find, and Next) also have their own individual
icons on the toolbar.
