Hid Class Draiver Skachat [BEST]



The header defines IOCTLs that a HID minidriver must support. Only the HID class driver sends these IOCTLs to a HID minidriver. User-mode applications and other kernel-mode drivers can only communicate with HID collections by using the HIDClass support routines and HID class driver IOCTLs.

A HID minidriver must handle a set of IOCTLs. Only the HID class driver sends these IOCTLs to a HID minidriver. User-mode applications and other kernel-mode drivers can only communicate with HID collections by using the HIDClass support routines and HID class driver IOCTLs.


Although user applications can communicate with the HID class driver by using HidD_Xxx HIDClass support routines, kernel-mode drivers must send the corresponding device control requests described in this section.


As described for each IOCTL, the Information member is set either by the class driver or a lower-level driver. Normally, when a lower-level driver transfers data from or to a device, the lower-level driver sets Information to the number of bytes transferred. However, the HID class driver might return a different value.


The HID class driver transparently manages and routes all communication between upper-level drivers and applications and the underlying input devices that support HID collections. It manages the different data protocols that are used by different input devices and input queues that support more than one open file on the same HID collection.


A HID minidriver sets its entry points in the driver object that the minidriver receives as input to its DRIVER_INITIALIZE routine. The HID minidriver sets these entry points before it registers with the HID class driver.


When the HID class driver's AddDevice routine is called to create a functional device object (FDO), the HID class driver creates the FDO, initializes it, and calls the HID minidriver AddDevice routine. The HID minidriver AddDevice routine does internal device-specific initialization and, if successful, returns STATUS_SUCCESS. If the HID minidriver AddDevice routine isn't successful, the HID class driver deletes the FDO and returns the status returned by the HID minidriver AddDevice routine.


When the HID class driver Unload routine is called, the HID class driver completes releasing all resources associated with FDO and calls the HID minidriver's Unload routine.


The following section talks about registering a WDM based HID minidriver but much of it's pertinent to a KMDF based Frameworks driver also. All HID minidriver must register with the HID class driver, and the HID class driver communicates with the minidriver by calling the minidriver's standard driver routines.


After a HID minidriver completes all other driver initialization in its DRIVER_INITIALIZE routine, the HID minidriver binds its operation to the HID class driver by calling HidRegisterMinidriver.


A HID minidriver device extension is device-specific, and is only used by a HID minidriver. The HID class driver allocates the memory for the minidriver device extension when the class driver creates its device extension for a functional device object (FDO). The HID minidriver specifies the size of its device extension when it registers the minidriver with the HID class driver. The size is specified by the DeviceExtensionSize member of a HID_MINIDRIVER_REGISTRATION structure.


A HID minidriver must use a HID_DEVICE_EXTENSION structure as the layout for the device extension created by the HID class driver for a functional device object (FDO). The HID class driver sets the members of this structure when it initializes the FDO. A HID minidriver must not change the information in this structure.


The HID class driver handles creating and initializing the functional device object (FDO) for an underlying input device. The HID class driver also operates the FDO from the perspective of the upper-level interface to the underlying device and its child devices (HID collections).


The parameters that are passed to the HID minidriver DRIVER_ADD_DEVICE routine are the minidriver driver object and the FDO. The HID class driver passes the FDO to the minidriver AddDevice routine, not to the physical device object for the underlying input device.


A HID minidriver must supply the following dispatch routines: create, close, internal device control, system control, Plug and Play, and power management. Except for internal device control requests, most of these dispatch routines provide minimal function. When the HID class driver calls these dispatch routines, it passes the minidriver driver object and the functional device object (FDO).


In compliance with WDM requirements, the HID class driver and a HID minidriver provide a dispatch routine for create requests. However, the FDO can't be opened. The HID class driver returns STATUS_UNSUCCESSFUL.


In compliance with WDM requirements, the HID class driver and a HID minidriver must provide a dispatch routine for close requests. However, the FDO can't be opened. The HID class driver returns STATUS_INVALID_PARAMETER_1.


The HID class driver does all the Plug and Play processing associated with the FDO. When the HID class driver processes a Plug and Play request, it calls the HID minidriver's Plug and Play dispatch routine.


If you are installing USB drivers: You don't need to download USB device class drivers. They're installed automatically. These drivers and their installation files are included in Windows. They're available in the \Windows\System32\DriverStore\FileRepository folder. The drivers are updated through Windows Update.


If you are writing a custom driver: Before writing a driver for your USB device, determine whether a Microsoft-provided driver meets the device requirements. If a Microsoft-provided driver isn't available for the USB device class to which your device belongs, then consider using generic drivers, Winusb.sys or Usbccgp.sys. Write a driver only when necessary. More guidelines are included in Choosing a driver model for developing a USB client driver.


USB device classes are categories of devices with similar characteristics and that perform common functions. The USB-IF defines those classes and their specifications. Each device class is identified by a USB-IF approved class, subclass, and protocol codes, all of which are provided by the IHV in device descriptors in the firmware. Microsoft provides in-box drivers for several of those device classes, called USB device class drivers. If a device that belongs to a supported device class is connected to a system, Windows automatically loads the class driver, and the device functions with no other driver required.


Hardware vendors shouldn't write drivers for the supported device classes. Windows class drivers might not support all of the features that are described in a class specification. If some of the device's capabilities aren't implemented by the class driver, vendors should provide supplementary drivers that work with the class driver to support the entire range of functionality provided by the device.


Microsoft defines setup classes for most devices. IHVs and OEMs can define new device setup classes, but only if none of the existing classes apply. For more information, see System-Defined Device Setup Classes.


USBDevice 88BAE032-5A81-49f0-BC3D-A4FF138216D6: IHVs must use this class for custom devices that don't belong to another class. This class isn't used for USB host controllers and hubs.


The device setup classes are different from USB device classes discussed earlier. For example, an audio device has a USB device class code of 01h in its descriptor. When connected to a system, Windows loads the Microsoft-provided class driver, Usbaudio.sys. In Device Manager, the device is shown under is Sound, video and game controllers, which indicates that the device setup class is Media.


When this issue occurs, the Sensor HID class driver rejects the device, and the user may see an HID sensor with a yellow bang in Device Manager. Additionally, certain Windows features that are dependent on sensor data, such as screen rotation and screen brightness, may stop functioning correctly.


Download the Samsung Mobile HIDClass Driver Win10 here. This driver is part of the Samsung Windows 10 anniversary update for 2017. The hidclass driver. Note that this is a cab file so you will need to install the file in a different way as explained below as to how to get Windows 10 to install the Samsung driver for this update. Its a very small file and this was released in February 2017 with the latest Windows 10 updates, and there have been many since then. First check to see if you have the correct hardware before you proceed.


The development of Microsoft Windows Operating System by Microsoft prompted the latest creation of hidclass.sys. It is also known as a Hid Class Library file (file extension SYS), which is classified as a type of Win64 DLL (Dynamic link library) file.


There are a number of reasons why you could be encountering issues with hidclass.sys. Most of the issues concerning SYS files involve Blue Screen of Death (BSOD) errors. These types of hidclass.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg. Microsoft Office Access 2010 update) issues. Some of these errors include:


GEEK TIP : As a rule of thumb, it's always a good idea to create a Windows "Snapshot" backup / System Restore Point before making any hardware or software changes to your computer. That way, it's very easy to restore your system in the unfortunate event you encounter a hidclass.sys Blue Screen of Death error after recent changes.


If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your hidclass.sys issue. These troubleshooting steps are listed in the recommended order of execution. 041b061a72
