如何检测硬件设备是否已通过 USB 端口从我的 PC 上插入或拔出

Question

Current effort: 1, hidapi-1.1.jar 2, GetRawInputDeviceList

hidapi-1.1.jar is aborted in my app for some reason.

GetRawInputDeviceList isn't stable in Win10 referring https://stackoverflow.com/questions/32419314/getrawinputdevicelist-and-getrawinputdeviceinfo-fail-to-work-in-win10

I wonder is there any other method to reach my goal? OS is windows, programming language is not limited.

Answer 1

You can use the hotplug event notification API present in libusb . Documentation is here: http://libusb.sourceforge.net/api-1.0/hotplug.html

In a nutshell, this API lets your program get a callback whenever a device is connected or disconnected, and lets you filter for just the devices you care about (see libusb_hotplug_register_callback ).

Note that the hotplug API isn't supported on all OSes; if it isn't, you will have to fallback to enumerating devices using libusb_get_device_list .

Answer 2

Actually SetupDiGetDeviceInstanceId can be used to monitor it. For details, pls refer to https://msdn.microsoft.com/en-us/library/windows/hardware/ff551106(v=vs.85).aspx .
