USB 驅動程式參考技術的概觀。 若要開發 USB 驅動程式參考,您需要下列標頭: genericusbfnioctl.h usbuser.h winusb.h winusbio.h 如需這項技術的程式設計指導方針,請參閱: USB 驅動程式參考 IOCTLs 展開表格 IOCTL_GENERICUSBFN_ACTI加值稅E_USB_BUS ...
USB设备驱动程序使用ID table来支持热插拔。usb_driver结构中包含的指针变量id_table指向usb_device_id类型的结构数组,该结构数组声明USB设备驱动程序支持的设备。大多数驱动程序使用USB_DEVICE()宏来创建usb_device_id结构。这些结构通过使用MODULE_DEVICE_TABLE(usb, xxx)宏注册到USB核心。类中包含的以下代码行/linux...

四、 linux内核下USB相关的API函数与数据结构 前面介绍了USB相关一些基础概念与重要的数据结构,接下来就分析在linux内核中如何编写一个USB 驱动程序,编写与一个USB设备驱动程序的方法和其他总线驱动方式类似...\n"); } //定义USB驱动结构体 static struct usb_driver usbtest_driver = { .name = "linux_usb_...
GetUSBDIVersionis deprecated in Windows 8 and later versions of the operating system. To determine whether a particular version is supported by the underlying USB driver stack, the client driver must callUSBD_IsInterfaceVersionSupported. Requirements ...
USB核心驱动:Linux内核设计的一个抽象层,目的是将Class Driver和USB Host Controller Driver分隔开。 USB设备驱动程序:与特定USB设备相对应的驱动程序,为USB设备提供具体的读写功能和其他控制功能。 USB主机控制器驱动:直接与硬件设备交互。 USB文件系统:如usbfs,提供用户空间访问USB设备的接口。
下面的代码示例演示客户端驱动程序的 EvtDriverDeviceAdd 事件回调实现。 C++ NTSTATUSMyUSBDriver_EvtDeviceAdd( _In_ WDFDRIVER Driver, _Inout_ PWDFDEVICE_INIT DeviceInit ){ NTSTATUS status; UNREFERENCED_PARAMETER(Driver); PAGED_CODE(); TraceEvents(TRACE_LEVEL_INFORMATION, TRACE_DRIVER,"%!FUNC! Entry...
