Generic USB Device Sample Details

This sample focuses on the core functionality of interacting with USB devices in user mode or kernel mode using the Windows Driver Frameworks. It includes:

• Device discovery and enumeration.
• Establishing communication channels (pipes).
• Performing bulk and interrupt transfers.
• Reading device configuration information.

// Example snippet (illustrative, not fully functional)
NTSTATUS
UsbdSample_ConfigureDevice(
    _In_ WDFUSBDEVICE UsbDevice
    )
{
    NTSTATUS status;
    WDF_USB_DEVICE_CREATE_CONFIG config;
    WDF_USB_DEVICE_CREATE_CONFIG_INIT(&config,
                                    WdfUsbDesignatorTypeVendorDefined,
                                    0,
                                    0); // Replace with actual configuration

    status = WdfUsbTargetDeviceCreateWithParameters(
        UsbDevice,
        &config,
        WDF_NO_OBJECT_ATTRIBUTES,
        WDF_NO_HANDLE // pUsbTargetDevice
        );

    if (!NT_SUCCESS(status)) {
        // Handle error
        return status;
    }

    // ... Further configuration and pipe handling ...

    return STATUS_SUCCESS;
}
