Keyboard and mouse HID client drivers • • 15 minutes to read • Contributors • • In this article This topic discusses keyboard and mouse HID client drivers. Keyboards and mice represent the first set of HID clients that were standardized in the HID Usage tables and implemented in Windows operating systems. Keyboard and mouse HID client drivers are implemented in the form of HID Mapper Drivers. A HID mapper driver is a kernel-mode WDM filter driver that provides a bidirectional interface for I/O requests between a non-HID Class driver and the HID class driver. The mapper driver maps the I/O requests and data protocols of one to the other. Windows provides system-supplied HID mapper drivers for HID keyboard, and HID mice devices. Architecture and overview The following figure illustrates the system-supplied driver stacks for USB keyboard and mouse/touchpad devices. Stowaway Keyboard Driver DownloadThe figure above includes the following components: • KBDHID.sys – HID client mapper driver for keyboards. Converts HID usages into scancodes to interface with the existing keyboard class driver. Targus Stowaway Keyboard Driver• MOUHID.sys – HID client mapper driver for mice/touchpads. Converts HID usages into mouse commands (X/Y, buttons, wheel) to interface with the existing keyboard class driver. • KBDCLASS.sys – The keyboard class driver maintains functionality for all keyboards and keypads on the system in a secure manner. • MOUCLASS.sys – The mouse class driver maintains functionality for all mice / touchpads on the system. The driver does support both absolute and relative pointing devices. This is not the driver for touchscreens as that is managed by a different driver in Windows. The system builds the driver stack as follows: • The transport stack creates a physical device object (PDO) for each HID device attached and loads the appropriate HID transport driver which in turn loads the HID Class Driver. • The HID class driver creates a PDO for each keyboard or mouse TLC. Complex HID devices (more than 1 TLC) are exposed as multiple PDOs created by HID class driver. For example, a keyboard with an integrated mouse might have one collection for the standard keyboard controls and a different collection for the mouse. • The keyboard or mouse hid client mapper drivers are loaded on the appropriate FDO. • The HID mapper drivers create FDOs for keyboard and mouse, and load the class drivers. Important notes: • Vendor drivers are not required for keyboards and mice that are compliant with the supported HID Usages and top level collections. • Vendors may optionally provide filter drivers in the HID stack to alter/enhance the functionality of these specific TLC. • Vendors should create separate TLCs, that are vendor specific, to exchange vendor proprietary data between their hid client and the device. Avoid using filter drivers unless critical. • The system opens all keyboard and mouse collections for its exclusive use. • The system prevents disable/enabling a keyboard. • The system provides support for horizontal/vertical wheels with smooth scrolling capabilities. Driver Guidance Microsoft provides the following guidance for IHVs writing drivers: • Driver developers are allowed to add additional drivers in the form of a filter driver or a new HID Client driver. The criteria are described below: • Filters Drivers: Driver developers should ensure that their value-add driver is a filter driver and does not replace (or be used in place of) existing Windows HID drivers in the input stack.
