HID Extensions

This section describes the Human Interface Device (HID) debugger extension commands.

The HID debugger extension commands are implemented in Hidkd.dll. To load the HID commands, enter .load hidkd.dll in the debugger.

Getting started with the HID extensions

To start debugging a HID issue, enter the !hidtree command. The !hidtree command displays a list of commands and addresses that you can use to investigate device objects, preparsed HID data, and HID report descriptors.
