对所有USB设备使用RegisterDeviceNotification（） [英] Use RegisterDeviceNotification() for ALL USB devices

问题描述

我目前有一些代码，用于在Windows服务（用C ++编写）中设置连接的USB HID设备的通知。代码如下：

I currently have some code that sets up notifications of connected USB HID devices within a Windows Service (written in C++). The code is as follows:

   GUID hidGuid;
   HidD_GetHidGuid(&hidGuid);

   DEV_BROADCAST_DEVICEINTERFACE NotificationFilter;
   ZeroMemory(&NotificationFilter, sizeof(NotificationFilter));
   NotificationFilter.dbcc_size = sizeof(DEV_BROADCAST_DEVICEINTERFACE);
   NotificationFilter.dbcc_devicetype = DBT_DEVTYP_DEVICEINTERFACE;
   NotificationFilter.dbcc_classguid = hidGuid;
   HDEVNOTIFY deviceNotify = RegisterDeviceNotification(StatusHandle, &NotificationFilter, DEVICE_NOTIFY_SERVICE_HANDLE);

然后通过SERVICE_CONTROL_DEVICEEVENT事件接收通知。 （记住，这是一个服务，所以没有WM_DEVICECHANGE）。

A notification is then received via the SERVICE_CONTROL_DEVICEEVENT event. (Remember, this is a Service so no WM_DEVICECHANGE).

我想我可以在RegisterDeviceNotification（）调用中指定DEV_BROADCAST_DEVICEINTERFACE标志，所以它会覆盖dbcc_classguid，设备，但事实证明，该标志不支持在Windows 2000，这是一个我的交易崩溃。

I thought I could just specify the DEV_BROADCAST_DEVICEINTERFACE flag in the RegisterDeviceNotification() call so it would override dbcc_classguid and get all devices, but it turns out that that flag is not supported on Windows 2000, which is a dealbreaker for me. Also, I'm guessing that that would return more than just USB devices.

我应该如何修改以获取所有 USB设备，而不是只是USB HID？应该是简单，只是给一个不同的GUID？

How should I modify this to get all USB devices, not just USB HID? Should it be as simple as just giving a different GUID? Is there even a GUID for all USB?

推荐答案

使用GUID_DEVINTERFACE_USB_DEVICE（在usbiodef.h中）观看所有USB设备。

Used GUID_DEVINTERFACE_USB_DEVICE (in "usbiodef.h") to watch for all USB devices.

  DEV_BROADCAST_DEVICEINTERFACE NotificationFilter;
  ZeroMemory(&NotificationFilter, sizeof(NotificationFilter));

  NotificationFilter.dbcc_size = sizeof(NotificationFilter);
  NotificationFilter.dbcc_devicetype = DBT_DEVTYP_DEVICEINTERFACE;
  NotificationFilter.dbcc_reserved = 0;

  NotificationFilter.dbcc_classguid = GUID_DEVINTERFACE_USB_DEVICE;

  HDEVNOTIFY hDevNotify = RegisterDeviceNotification(hwnd, &NotificationFilter, DEVICE_NOTIFY_SERVICE_HANDLE);
