Welcome to USB Driver Documentation
This guide provides comprehensive information for developing, testing, and debugging USB drivers on Windows. Navigate through the sections on the left to explore topics ranging from driver architecture to sample code.
Getting Started
Before you begin, ensure you have the Windows Driver Kit (WDK) installed and a basic understanding of the Windows driver model.
Key Concepts
- USB driver stack and its layers
- URB (USB Request Block) handling
- Power management for USB devices
- Device enumeration and descriptor parsing
Sample Code Snippet
// Minimal skeleton of a USB driver entry point
#include <ntddk.h>
#include <wdf.h>
DRIVER_INITIALIZE DriverEntry;
EVT_WDF_DRIVER_DEVICE_ADD UsbEvtDeviceAdd;
NTSTATUS DriverEntry(PDRIVER_OBJECT DriverObject, PUNICODE_STRING RegistryPath)
{
WDF_DRIVER_CONFIG config;
WDF_DRIVER_CONFIG_INIT(&config, UsbEvtDeviceAdd);
return WdfDriverCreate(DriverObject, RegistryPath, WDF_NO_OBJECT_ATTRIBUTES, &config, WDF_NO_HANDLE);
}
NTSTATUS UsbEvtDeviceAdd(WDFDRIVER Driver, PWDFDEVICE_INIT DeviceInit)
{
// Device initialization logic here
return STATUS_SUCCESS;
}
