In the one-to-one mode , each device has an independent device stack. The class driver creates and attaches an independent class DO to each device stack. Each device stack has its own control state and input buffer.

The Microsoft Win32 subsystem accesses input from each device through a unique file object. In the grandmaster mode , the class driver operates all the devices in the following way:. The class driver creates both a grandmaster class DO that represents all of the devices and a subordinate class DO for each device. The class driver attaches a subordinate class DO to each device stack. Below the subordinate class DO, the device stack is same as that created in the one-to-one mode.

The Win32 subsystem accesses all device input through the file object that represents the grandmaster class device. Otherwise Kbdclass and Mouclass operate in grandmaster mode. The Microsoft Win32 subsystem opens all keyboard and mouse devices for its exclusive use.

For each device class, the Win32 subsystem treats input from all the devices as if the input came from a single input device. An application cannot request to receive input from only one particular device.

The Win32 subsystem closes Plug and Play devices after it receives notification that an opened interface is disabled. Note that once the Win32 subsystem successfully opens a legacy device, it cannot determine if the device is later physically removed. After Kbdclass and Mouclass receive a create request they do the following for Plug and Play and legacy operation:.

Otherwise the class driver completes the request without sending the request down the driver stack. The class driver sets the trusted file that has read access to the device. If there is a grandmaster device, the class driver sends a create request to all the ports that are associated with the subordinate class devices. The class driver sends an internal device control request to the port driver to enable the device. The class drivers must connect their class service to a device before the device can be opened.

The class drivers connect their class service after they attach a class DO to a device stack. The function driver uses the class service callback to transfer input data from a device to the class data queue for the device. The function driver's ISR dispatch completion routine for a device calls the class service callback.

A vendor can modify the operation of a class service callback by installing an upper-level filter driver for a device. The sample filter service callbacks can be configured to modify the input data that is transferred from the port input buffer for a device to the class data queue.

For example, the filter service callback can delete, transform, or insert data. After the filter driver receives the connect request, it saves a copy of the class connect data, and replaces the request's connect data with filter connect data.

The filter connect data specifies a pointer to the filter device object and a pointer to the filter driver service callback. Please follow the steps below to download and properly replace you file:.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process.

If you are not currently backing up your data, you need to do so immediately. Microsoft typically does not release Windows SYS files for download because they are bundled together inside of a software installer.

The installer's task is to ensure that all correct verifications have been made before installing and placing mouclass. An incorrectly installed SYS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
