The driver contains two parts: The driver for the AD7780 part, which may be used, without modifications, with any microcontroller. The Communication Driver, where the specific communication functions for the desired type of processor and communication protocol have to be implemented. The device can be configured to have four differential inputs or eight pseudo differential inputs. The on-chip channel sequencer allows several channels to be enabled simultaneously, and the AD7193 sequentially converts on each enabled channel, simplifying communication with the part. The smartpqi driver is the next generation SCSI driver for Microchip Corp. The smartpqi driver is the first SCSI driver to implement the PQI queuing model. The smartpqi driver will replace the aacraid driver for Adaptec Series 9 controllers. Customers running an older kernel (Pre-4.9) using an Adaptec Series 9 controller will have to configure.

You can use Windows' built-in HID (human interface device) drivers to communicate with devices that conform to the USB's HID class specification. There's no need for a custom driver; the device uses the drivers included in Windows. Use any programming language that supports calling API functions. The device doesn't have to have a 'human interface.' Any device that can function within the limits of the HID specification (control and interrupt transfers only) may be able to be designed as a HID.
Microsoft's WDK has documentation for the HID functions and an overview of how to use them. The WDK also includes the header files to use with Visual C++ programs that access HID-class devices (hidsdi.h, hidusage.h, hidpi.h).

Microsoft's DirectX technology includes DirectInput, which supports communications with HID-class game controllers (in both directions, in spite of the name), without requiring custom drivers. Developing Games from Microsoft has more information.

Host applications and device firmware to work with them. Thank you to everyone who has helped by contributing bug reports and often the fixes along with them.
My HID applications below communicate with generic (custom) HIDs. Each supports exchanging Input, Output, and Feature reports and shows how to search for devices that use a particular interface GUID. All except the Visual Basic 6 code show how to use RegisterDeviceNotification and WM_DEVICE_CHANGE messages to detect when a device is attached or removed.
There are two versions of the application. One uses Filestreams; the other uses ReadFile and WriteFile.
Discussion about using Filestreams vs. ReadFile and WriteFile.

To use my generic_hid project in Windows 10, open the .csproj file in Notepad or another text editor and delete this information, which relates to the signing certificate:
Visual C# (C Sharp)
generic_hid_cs_62. Created with Visual Studio 2012 for the .NET Framework 4.5 or later. Uses v4.5's Filestream ReadAsync and WriteAsync methods. Uses System.Management class (WMI) to detect device arrival and removal. Requires Windows Vista or later and an attached USB generic Human Interface Device (HID). This application does not run on Windows XP or earlier because the .NET 4.5 Framework will not install on these OSes. Created 11/12/13.
generic_hid_cs_60. Created with Visual Studio 2012 for the .NET Framework 4.5 or later. Uses v4.5's Filestream ReadAsync and WriteAsync methods. Requires Windows Vista or later and an attached USB generic Human Interface Device (HID).This application does not run on Windows XP or earlier because the .NET 4.5 Framework will not install on these OSes. Created 2/11/13.
generic_hid_cs_50. Created with Visual Studio 2008 for the .NET Framework 2.0 or later. Uses Filestreams. Updated 4/1/11.
generic_hid_cs_46. Created with Visual Studio 2008 for the .NET Framework 2.0 or later. Uses ReadFile and WriteFile.

Usbhidio_vc6. This project will load into and run in Visual Studio. The project requires the header files hid.lib, hid.h, and hidsdi.h from the WDK.
1. If you get this errror on attempting to compile:
DBT_DEVTYP_DEVICEINTERFACE, PDEV_BROADCAST_DEVICEINTERFACE, HDEVNOTIFY, DEVICE_NOTIFY_WINDOW_HANDLE undeclared
Set WINVER = 0x0500 or higher in stdafx.h
For more info, go to groups.google.com and search on:
