📒 笔记文档

• 设备初始化

  #include "../../include/HCUsbSDK.h"
  if (!USB_Init()) { printf("USB_Init failed\n"); return -1; }
  

• 获取已连接的设备数量

  int count = USB_GetDeviceCount();
  printf("DeviceCount=%d\n", count);
  if (count <= 0) 
  {     
      USB_Cleanup();
  	return -1;
  }
  

• 遍历设备

  USB_DEVICE_INFO *devices = malloc(sizeof(USB_DEVICE_INFO) * count);
  if (!USB_EnumDevices(count, devices))
  {
      free(devices);
      USB_Cleanup();
      return -1;
  }
  printf("Device: type=%d name=%s\n",devices[0].byProtocolType,devices[0].szDeviceName);
  

• 登录设备0

  /* ========== 登录设备 ========== */
  USB_USER_LOGIN_INFO li = {0};
  USB_DEVICE_REG_RES  lr = {0};
  li.dwSize = sizeof(li);
  li.dwTimeout = 5000;
  li.dwVID = devices[0].dwVID;
  li.dwPID = devices[0].dwPID;
  memcpy(li.szSerialNumber, devices[0].szSerialNumber, MAX_SERIAL_NUMBER_LEN);
  memcpy(li.szUserName, "admin", 5);
  memcpy(li.szPassword, "12345", 5);
  li.byLoginMode = 1;
  lr.dwSize = sizeof(lr);
  
  LONG userId = USB_Login(&li, &lr);
  if (userId < 0)
  {
      printf("Login failed, err=%d\n", USB_GetLastError());
      free(devices);
      USB_Cleanup();
      return -1;
  }
