Provides common declarations shared by the client driver and user applications that communicate with the USB 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.

Good Luck. Yes Leo, I totally agreed with you that Not Responding message in title bar is quite legal and legitimate while Windows especially Vista is performing lenhthy operation.

Very frustrating indeed! Just wonder why Microsoft is not trying hard enough to resolve this problem after so many complaints in such a long time! The interesting factor is that I have 2 computers. I swapped the 2 machines and it happened again…more on the swapped one than the other. Ever heard on an internet connection being the culprit?
Hello Leo I can see by the comments that tons of folk are having the not responding prob on XP, but from what i can see is that we still do not know what to do about it. If left alone the process will finish and the program will return to normal responding state, however it is nice to be able to see the feedback that the program is giving to monitor the process.
The process runs and responds flawlessly in Windows XP. My home page looked different at the top, everything started saying, not responding, internet explorer would freeze and say not responding, then it would come back, then it would say Microsoft is not responding, after it comes back then msn or bing is not responding, one after another.
