The Microsoft Win32 subsystem opens all keyboard and mouse devices for its exclusive use. Otherwise Kbdclass and Mouclass operate in grandmaster mode. Kbdclass and Mouclass operate in the one-to-one mode if their registry entry value ConnectMultiplePorts is set to 0x00 (under the key HKLM\Services\CurrentControlSet\ \Parameters, where class service is Kbdclass or Mouclass). The grandmaster maintains a single global device state. The Win32 subsystem accesses all device input through the file object that represents the grandmaster class device.Īll device input is buffered in the grandmaster's data queue. The grandmaster class DO controls the operation of all the subordinate DOs. Below the subordinate class DO, the device stack is same as that created in the one-to-one mode.

The class driver attaches a subordinate class DO to each device stack. The class driver creates both a grandmaster class DO that represents all of the devices and a subordinate class DO for each device. In the grandmaster mode, the class driver operates all the devices in the following way: The Microsoft Win32 subsystem accesses input from each device through a unique file object. Each device stack has its own control state and input buffer. The class driver creates and attaches an independent class DO to each device stack. In the one-to-one mode, each device has an independent device stack. Kbdclass and Mouclass can support more than one device in two different modes.

One or more optional upper-level mouse filter driver.

Mouclass, the upper-level mouse class filter driver.

The mouse driver stack consists of the following.

One or more optional upper-level keyboard filter driver.

Kbdclass, the upper-level keyboard class filter driver.

The keyboard driver stack consists of the following. I8042prt creates the function DO and attaches it to a physical device object ( PDO) created by the root bus driver. An upper-level device filter driver creates the upper-level device filter DO. Each class driver creates an upper-level class filter device object (filter DO) that is attached to a function device object ( FDO) through an optional upper-level device filter DO. The following figure shows the configuration of device objects for a Plug and Play PS/2-style keyboard and mouse device. Simultaneous operation of more than one device.Ĭonnection of a class service callback routine that a function driver uses to transfer data from the input data buffer of the device to the data buffer of the class driver.

Plug and Play, power management, and Windows Management Instrumentation (WMI). Generic and hardware-independent operation of the device class. Mouclass implements the Mouclass service and its executable image is mouclass.sys. Kbdclass implements the Kbdclass service and its executable image is kbdclass.sys. Mouclass, the class driver for devices of GUID_CLASS_MOUSE device class Kbdclass, the class driver for devices of GUID_CLASS_KEYBOARD device class This topic describes the features of the following Microsoft Windows 2000 and later system class drivers:

Windows does not support independent access by a client to each device.

Windows supports the simultaneous connection of more than one keyboard and mouse device.

Keyboards are opened in exclusive mode by the operating system stack for security reasons.

The following additional information is important for keyboard and mouse manufacturers:

A typical configuration consists of a PS/2-style keyboard operated through an i8042 controller, and a serial-style mouse operated through a serial port controller. The figure on the left shows a keyboard and a mouse connected to a system bus through independent controllers. The following figures show two common configurations that employ a single keyboard and a single mouse. This topic describes the typical physical configuration of keyboard and mouse devices in Microsoft Windows 2000 and later. The following sections goes into details on the controllers.

This section contains details on the class drivers themselves. Non-HID keyboards and mice can connect over multiple legacy buses but still use the same class driver. Troubleshoot a wireless mouse that does not function correctly.Mouse, touchpad, and keyboard problems in Windows.
