It requires the .NET Framework V2.0 or later. Purpose: Demonstrates USB communications with a generic HID-class device Requirements: Windows *** or later and an attached USB generic Human Interface Device (HID). Description: Finds an attached device that matches the vendor and product IDs in the form's text boxes. Retrieves the device's capabilities. Sends and requests HID reports. Uses RegisterDeviceNotification() and WM_DEVICE_CHANGE messages to detect when a device is attached or removed. RegisterDeviceNotification doesn't work under Windows *** (not sure why). A list box displays the data sent and received, along with error and status messages. Combo boxes select data to send, and 1-time or timed, periodic transfers. You can change the size of the host's Input report buffer and request to use control transfers only to exchange Input and Output reports. To view additional debugging messages, in the Visual Studio development environment, select the Debug build (Build > Configuration Manager > Active Solution Configuration) and view the Output window (View > Other Windows > Output) The application uses a Delegate and the BeginInvoke and EndInvoke methods to read Input reports asynchronously, so the application's main thread doesn't have to wait for the device to return an Input report when the HID driver's buffer is empty. If you want to only receive data or only send data, comment out the unwanted code (In ExchangeInputAndOutputReports or ExchangeFeatureReports, comment out the "Success = " line and the "If Success" block that follows it). This project includes the following modules: GenericHid.vb - runs the application. FrmMain.vb - routines specific to the form. Hid.vb - routines specific to HID communications. DeviceManagement.vb - routines for obtaining a handle to a device from its GUID and receiving device notifications. This routines are not specific to HIDs. Debugging.vb - contains a routine for displaying API error messages. HidDeclarations.vb - Declarations for API functions used by Hid.vb. FileIODeclarations.vb - Declarations for file-related API functions. DeviceManagementDeclarations.vb - Declarations for API functions used by DeviceManagement.vb. DebuggingDeclarations.vb - Declarations for API functions used by Debugging.vb. Companion device firmware for several device CPUs is available from www.Lvr.com/hidpage.htm. You can use any generic HID (not a system mouse or keyboard) that sends and receives reports. New in V2.4: To eliminate VB6 "upgrade support" code, added GenericHid.vb file. Uses XML comments. Uses SafeFileHandle and SafeWaitHandle instead of IntPtr in "file" and wait operations. The Namespace, Assembly, and Root Namespace are all titled "GenericHid". The Solution is titled "GenericHid_vb". Other minor refinements. New in version 2.3: In the asychronous ReadFiles, the GetInputReportData callback routine uses marshaling to perform actions on the form, which runs in a different thread. The marshaling is required by the .NET Framework 2.0. I also fixed a few other things that the compiler complained about. New in version 2.2: The application obtains separate handles for device information/Feature reports, Input reports, and Output reports. This enables getting information about mice and keyboards. The application detects if the device is a mouse or keyboard and warns that Windows 2000/XP will not allow exchanging Input or Output reports. The list box's contents are trimmed when they get too large. For more information about HIDs and USB, and additional example device firmware to use with this application, visit Lakeview Research at http://www.Lvr.com .
