Use RegisterDeviceNotification() for ALL USB devices
提问by Adam Haile
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:
我目前有一些代码可以在 Windows 服务（用 C++ 编写）中设置连接的 USB HID 设备的通知。代码如下：
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);
A notification is then received via the SERVICE_CONTROL_DEVICEEVENT event. (Remember, this is a Service so no WM_DEVICECHANGE).
然后通过 SERVICE_CONTROL_DEVICEEVENT 事件接收通知。（请记住，这是一项服务，因此没有 WM_DEVICECHANGE）。
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.
我以为我可以只在 RegisterDeviceNotification() 调用中指定 DEV_BROADCAST_DEVICEINTERFACE 标志，这样它就会覆盖 dbcc_classguid 并获取所有设备，但事实证明 Windows 2000 不支持该标志，这对我来说是一个破坏者。另外，我猜这将返回的不仅仅是 USB 设备。
How should I modify this to get allUSB devices, not just USB HID? Should it be as simple as just giving a different GUID? Is there even a GUID for all USB?
我应该如何修改它以获取所有USB 设备，而不仅仅是 USB HID？它应该像提供不同的 GUID 一样简单吗？甚至所有 USB 都有一个 GUID 吗？

Used GUID_DEVINTERFACE_USB_DEVICE (in "usbiodef.h") to watch for all USB devices.
使用 GUID_DEVINTERFACE_USB_DEVICE（在“usbiodef.h”中）来监视所有 USB 设备。
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);

Have you tried GUID_DEVCLASS_USB? (defined in devguid.h, Windows SDK)
你试过GUID_DEVCLASS_USB吗？（在 devguid.h 中定义，Windows SDK）
Did you mean the DEVICE_NOTIFY_ALL_INTERFACE_CLASSESflag?
你说的是DEVICE_NOTIFY_ALL_INTERFACE_CLASSES国旗吗？
Also, I found the following article helpful - it's about device GUIDs vs interface GUIDs:
此外，我发现以下文章很有帮助 - 它是关于设备 GUID 与界面 GUID：
