Initial commit: Complete USB2CAN cross-platform framework

Features:
- Cross-platform support (Windows/Linux/macOS)
- CAN and CANFD protocol support
- USB communication (WinUSB/libusb)
- Device management and configuration
- Message transmission and reception
- Filter configuration
- CMake build system
- Comprehensive examples and tests

+# USB2CAN功能框架
+
+这是一个跨平台的USB2CAN功能框架，支持Linux、CAN和USB，并且USB支持WinUSB。
+
+## 框架结构
+
+- **平台抽象层**: 处理不同操作系统（Windows、Linux）的差异
+- **USB通信层**: 处理USB通信，支持WinUSB
+- **CAN协议层**: 处理CAN和CANFD协议
+- **设备管理层**: 管理USB2CAN设备
+- **应用接口层**: 提供简化的API给应用程序使用
+

+
+## 使用方法
+
+1. 包含头文件：`#include "usb2can/api/Usb2Can.h"`
+2. 创建Usb2Can对象
+3. 初始化设备
+4. 发送/接收CAN报文
+5. 关闭设备
+
+## 示例代码
+
+```cpp
+#include "usb2can/api/Usb2Can.h"
+#include <iostream>
+
+int main() {
+    Usb2Can can;
+    
+    // 扫描设备
+    int deviceCount = can.scanDevices();
+    std::cout << "Found " << deviceCount << " devices" << std::endl;
+    
+    if (deviceCount > 0) {
+        // 打开第一个设备
+        if (can.openDevice(0)) {
+            // 初始化CAN
+            CanConfig config;
+            config.baudrate = 500000; // 500kbps
+            if (can.initCan(0, config)) {
+                // 发送CAN报文
+                CanMsg msg;
+                msg.id = 0x123;
+                msg.dataLength = 8;
+                memcpy(msg.data, "TestData", 8);
+                can.transmit(0, &msg, 1);
+                
+                // 接收CAN报文
+                CanMsg recvMsg;
+                if (can.receive(0, &recvMsg, 1, 1000)) {
+                    std::cout << "Received CAN message with ID: 0x" << std::hex << recvMsg.id << std::endl;
+                }
+            }
+            
+            // 关闭设备
+            can.closeDevice(0);
