windows usb 驱动 DLL APP 框架

article 2025/9/16 2:13:09

windows-x86 这块 做 host
freertos-stm32-usb-msc 这块 做 device

整体框架

python  -> pyusb -> pyusb backend -> usb devicepython代码 : https://blog.csdn.net/weixin_42967006/article/details/108755972或全局搜索 python代码pyusb的安装pip install pyusbpyusb backend 包括如下 // 现(2021-7-29 14:15:46) 主要由两个组织提供,仅需安装即可usb 驱动// 安装驱动成功后才能(在设备插入usb时)在设备管理器的通用串行总线控制器中查找到 该设备 usb dll// 和 usb 驱动进行通信

谁能提供 usb dll 和 usb driver

Cypress 公司

Cypress是一个公司 //an Infineon Technologies CompanyEZ-USB是 CyPress 开发的 8051 单片机 的 一个系列名参考 https://www.keil.com/dd/chip/3190.htmThe Cypress EZ-USB (AN21XX) is a High-speed 8051-based USB Device with Two UARTs, Dual DPTRs, 13 Interrupts / 4 Priority Levels, 24 I/O Lines, 3 Timers/Counters, 3.3V Operation, ROMless, 256 Bytes On-chip RAM, and 4K or 8K Bytes XRAM.CyPress 公司 的USB驱动 有两种cyusb.sys 是 新的USB驱动 规范ezusb.sys 是很久以前推出的USB驱动规范cyusb是CyPress 公司新的USB驱动规范文件包括cyusb.sys和cyusb.inf和cyusb.catsys是驱动程序二进制文件inf是驱动程序的配置文件cat是驱动程序的数字证书其中cyusb.inf文件中没有默认指定任何VID&PID，相关数字都以XXXX代替Cypress 给开发者提供了什么接口1.0 时代驱动 : cyusb.sys2.0 时代 // Cypress USBSuite驱动 : cyusb.sysC++  : cyapi.lib // 封装了驱动 C# 	 : cyusb.dll // 封装了驱动 // C# 不能直接调用 cyapi.lib// C++  能直接调用 cyapi.lib 和 cyusb.dll// 对于C++ 来说, cyapi.lib 提供 静态链接, cyusb.dll 提供动态链接Cypress 提供 dll 吗?提供,名称叫 CyUSB.dllhttps://www.cypress.com/file/121076/downloadEZ-USB FX3 Software Development Kit https://www.cypress.com/documentation/software-and-drivers/ez-usb-fx3-software-development-kitCypress 支持 linux 吗?支持 ,在 https://www.cypress.com/documentation/software-and-drivers/ez-usb-fx3-software-development-kit 中有 SDK "EZ-USB FX3 SDK 1.3.4 for Linux"

第一种方法

WinUSB(libusb) + libusb // libusb 需要额外安装winusb(libusb) 提供 driverlibusb 提供 dll // https://github.com/libusb/libusb/wiki/Windows

第二种方法

libusb-win32提供了 driver 和 dll

第三种方法

libusbK提供了 driver 和 dll

The DLL is part of the driver and installed automatically to the Windows system directory.libusbK // libusbK (v3.0.7.0)// 包括 驱动(支持HID) 和DLLlibusbK is a complete driver/library solution for vendor class usb device interfaces. If you are a usb developers or usb device manufacturer seeking a driver solution for a new USB widget then libusbK could be for you.libusbK encompasses a 100% WinUSB compatible api/funtion set. All WinUSB power/pipe polices are fully supported by the libusbK driver. In Addition, libusbK has full support for isochronous endpoints and an extensive set of additional modules to simplify development.libusbK is a Windows only project which provides a new set of API for Windows (supporting WinUSB, libusb0.sys and libusbk.sys) and kernel driver libusbK.sys.libusbK (http://libusbk.sourceforge.net/UsbK3/index.html) is the next-generation libusb-win32 kernel driver and associated library. The kernel driver (libusbK.sys) is based on KMDF and it will work with either libusb-win32 API or native libusbK API. The library (libusbK.dll) works with libusb0.sys, libusbK.sys and winusb.sys . It has dual licenses (Modified BSD and GPL).Currently libusbK is under active development. On the other hand, libusb0.sys and libusb-win32 API will still be supported (bug fix mode) even though no new features will be added.NO 	// WinUSB(Microsoft)WinUSB is a generic driver for USB devices that is included with all versions of Windows since Windows Vista. It includes:A kernel-mode driver (Winusb.sys)A user-mode dynamic link library (Winusb.dll) that exposes WinUSB functions described in winusb.h. You can use these functions to manage USB devices with user-mode software.By default, Winusb.sys is installed in the device's kernel-mode stack as an upper filter driver, and apps communicate with the device's UMDF function driver to issue read, write, or device I/O control requests. In this configuration, Winusb.sys serves as the device stack's Plug and Play and power owner.Alternatively, you can install Winusb.sys as the function driver for a USB device.USB Serial (CDC) // NO...
