visual-c++ - 不使用Windows驱动程序工具包列出具有指定VID和PID的USB设备

Question

有没有一种方法可以找到Windows上具有指定VID和PID的USB设备，而无需调用WDK函数？

Answer 1

这是郭彦超代码的简化版本:

unsigned index;
HDEVINFO hDevInfo;
SP_DEVINFO_DATA DeviceInfoData;
TCHAR HardwareID[1024];

// List all connected USB devices
hDevInfo = SetupDiGetClassDevs(NULL, TEXT("USB"), NULL, DIGCF_PRESENT | DIGCF_ALLCLASSES);
for (index = 0; ; index++) {
    DeviceInfoData.cbSize = sizeof(DeviceInfoData);
    if (!SetupDiEnumDeviceInfo(hDevInfo, index, &DeviceInfoData)) {
        return false;     // no match
    }

    SetupDiGetDeviceRegistryProperty(hDevInfo, &DeviceInfoData, SPDRP_HARDWAREID, NULL, (BYTE*)HardwareID, sizeof(HardwareID), NULL);

    if (_tcsstr(HardwareID, _T("VID_1234&PID_5678"))) {
        return true;     // match
    }
}
